Check Digit Verification of cas no

The CAS Registry Mumber 7623-13-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,6,2 and 3 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 7623-13:
(6*7)+(5*6)+(4*2)+(3*3)+(2*1)+(1*3)=94
94 % 10 = 4
So 7623-13-4 is a valid CAS Registry Number.

Preparation and preservation method of 2-chloro-N-n-octyl acrylamide

-

Paragraph 0016; 0017, (2017/08/30)

The invention discloses a preparation and preservation method of 2-chloro-N-n-octyl acrylamide. The 2-chloro-N-n-octyl acrylamide is an impurity concomitant with production of DCOIT, and the prepared high-purity 2-chloro-N-n-octyl acrylamide has a role in guiding production of the DCOIT. The method comprises that 2,3-methyl dichloropropionate is subjected to three-step reaction of hydrolysis, acylating chlorination and amination dehydrochlorination to obtain the final product, and an antioxidant is added in purification and preservation processes and can prevent polymerization metamorphism of the product.

Reaction of (α-halogenoalkyl)thiiranes with nucleophilic reagents I. Reaction with morpholine

Tomashevskii, A. A.,Sokolov, V. V.,Potekhin, A. A.

, p. 1610 - 1618 (2007/10/03)

By means of deuterated compounds it was established that (chloromethyl)thiirane reacts with morpholine by a mechanism involving initial opening of the thiirane ring followed by recyclization.In the case of (bromomethyl)thiirane direct substitution of the bromine begins to compete with this mechanism. 2-Methyl-2-(chloromethyl)thiirane, 2,2-dimethyl-3-(chloromethyl)thiirane, and the diastereomeric (1-chloroethyl)thiiranes were synthesized, and their reactivity toward morpholine was studied.

α-FLUOROACRYLIC ACID CHLORANHYDRIDE

Boguslavskaya, L. S.,Morozova, T. V.

, p. 716 - 720 (2007/10/02)

Kinetic studies were carried out on the reaction of 2-fluoro-3-chloropropanoic acid and other halo- and methoxy-substituted propanoic acids with thionyl chloride at 50-110 deg C.The catalytic dehydro-chlorination of 2-fluoro-3-chloropropanoic acid chloranhydride by tertiary amines and their salts was investigated.Dimethylaniline chlorohydrate was shown to be an effective catalyst, providing maximum dehydrochlorination at a concentration of 20percent.A mechanism for the reaction was proposed.
