Check Digit Verification of cas no

The CAS Registry Mumber 121794-95-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,7,9 and 4 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 121794-95:
(8*1)+(7*2)+(6*1)+(5*7)+(4*9)+(3*4)+(2*9)+(1*5)=134
134 % 10 = 4
So 121794-95-4 is a valid CAS Registry Number.

Asymmetric Petasis Borono-Mannich Allylation Reactions Catalyzed by Chiral Biphenols

Jiang, Yao,Schaus, Scott E.

, p. 1544 - 1548 (2017/02/05)

Chiral biphenols catalyze the asymmetric Petasis borono-Mannich allylation of aldehydes and amines through the use of a bench-stable allyldioxaborolane. The reaction proceeds via a two-step, one-pot process and requires 2–8 mole % of 3,3′-Ph2-BINOL as the optimal catalyst. Under microwave heating the reaction affords chiral homoallylic amines in excellent yields (up to 99 %) and high enantioselectivies (er up to 99:1). The catalytic reaction is a true multicomponent condensation reaction whereas both the aldehyde and the amine can possess a wide range of structural and electronic properties. Use of crotyldioxaborolane in the reaction results in stereodivergent products with anti- and syn-diastereomers both in good diastereoselectivities and enantioselectivities from the corresponding E- and Z-borolane stereoisomers.

Enantioselective transfer aminoallylation: Synthesis of optically active homoallylic primary amines

Sugiura, Masaharu,Mori, Chieko,Kobayashi, Shu

, p. 11038 - 11039 (2007/10/03)

A camphorquinone-derived chiral homoallylic amine was found to react with various aldehydes via imine formation and asymmetric 2-azonia-Cope rearrangement to give optically active homoallylic primary amines. A practical level of enantioselectivity with hi
