Check Digit Verification of cas no

The CAS Registry Mumber 2938-48-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,9,3 and 8 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 2938-48:
(6*2)+(5*9)+(4*3)+(3*8)+(2*4)+(1*8)=109
109 % 10 = 9
So 2938-48-9 is a valid CAS Registry Number.

VITRIFIED STATE STABILIZING AGENT FOR ANIMAL CELL CRYOPRESERVATION SOLUTION

-

, (2018/06/29)

Provided are a vitrification stabilizer for animal cell cryopreservation fluid, and an animal cell cryopreservation fluid that exhibits superior vitrification capacity due to containing said vitrification stabilizer for animal cell cryopreservation fluid. The vitrification stabilizer for animal cell cryopreservation fluid contains an amphoteric polymer compound selected from the group consisting of: (a) an amphoteric polymer compound obtained by reacting ?-poly-L-lysine with butyl succinic acid anhydride and performing carboxylation; (b) an amphoteric polymer compound obtained by reacting ?-poly-L-lysine with butyl succinic acid anhydride and succinic acid anhydride, and performing carboxylation; and (c) an amphoteric polymer compound obtained by reacting ?-poly-L-lysine with a compound represented by formula (I) and performing carboxylation.

-

Paragraph 00109, (2017/09/21)

The present invention relates to carotenoid-oxygen copolymers, compositions, methods of identifying and quantifying carotenoid-oxygen copolymers in food and related sources, and methods of producing compositions comprising same. In one aspect the method of identifying and quantifying carotenoid-oxygen copolymers comprises an analysis of a low molecular weight marker compound in said sources. In another aspect the present invention provides a method of preparing compositions comprising said carotenoid-oxygen copolymers and/or enhancing levels of said copolymers in food sources in a sufficient and practically useful concentration to have beneficial effects in animals and humans, including beneficial immunological and health effects.

Regioselective photochemical rearrangement of N-mesyloxylactams

Pichette, Simon,Aubert-Nicol, Samuel,Lessard, Jean,Spino, Claude

supporting information; experimental part, p. 1328 - 1335 (2012/04/05)

N-Mesyloxylactams can undergo ring contraction either by C-3 (usually observed) or C-5 migration. C-5 migration can occur when the C-3 migration product possesses ring strain, but it does not usually compete with C-3 migration. The greater preference for C-3 migration is due to the carbonyl oxygen atom, which greatly stabilizes the intermediate. Studies of the photochemical rearrangement of N-mesyloxylactams showed that the lone pair of the carbonyl oxygen atom, and not the degree of the substitution atthe migrating carbon atoms, is the governing factor in the regioselectivity of the reaction.

Synthesis of Small-Medium Ring Thioanhydrides

Kates, Michael J.,Schauble, J. Herman

, p. 971 - 978 (2007/10/02)

Reaction of five-membered ring anhydrides with sodium sulfide has previously been employed for synthesis of the corresponding thioanhydrides in low yields.Re-examination of the stoichiometry reveals reaction of cyclic anhydride with sodium sulfide (2:1 respectively), affords the thioanhydride accompanied by the corresponding dicarboxylate in a 1:1 molar ratio.The mechanistic pathway for this reaction has also been elucidated.Optimization of reaction conditions has resulted in the synthesis of a variety of four to seven-membered ring thioanhydride in yields approaching theoretical.
