Check Digit Verification of cas no

The CAS Registry Mumber 79929-43-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,9,9,2 and 9 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 79929-43:
(7*7)+(6*9)+(5*9)+(4*2)+(3*9)+(2*4)+(1*3)=194
194 % 10 = 4
So 79929-43-4 is a valid CAS Registry Number.

, p. 51991 - 51994 (2014)

An efficient and eco-friendly protocol has been developed for the preparation of n-alkyl terminal halohydrin esters under solvent- and catalyst-free conditions. Ring opening of cyclic ethers by organic acid halides affords the 1,4- and 1,5-halohydrins, OH-protected by different acyl groups. The green reaction conditions, simple work-up procedures, high yields and broad substrate scope of the reaction highlight the positive features of this method. This journal is
