Check Digit Verification of cas no

The CAS Registry Mumber 136194-40-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,6,1,9 and 4 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 136194-40:
(8*1)+(7*3)+(6*6)+(5*1)+(4*9)+(3*4)+(2*4)+(1*0)=126
126 % 10 = 6
So 136194-40-6 is a valid CAS Registry Number.

TELOMERISATION DES ETHERS VINYLIQUES ET LEUR COTELOMERISATION AVEC LES MONOMERES FLUORES

Boutevin, B.,Cersosimo, F.,Youssef, B.

, p. 403 - 418 (1991)

Radical cotelomerisation of vinylic ethers VE (butyl vinyl ether and 2-acetoxy ethyl vinyl ether) with chlorotrifluoroethylene and mercaptans (2-hydroxy ethyl mercaptane and C6F13C2H4SH) are studied.The homo-telomerization of vinylic ethers with these thiols and CCl3CH2OH leads to complex mixtures including acetals obtained by addition of the VE to hydroxy groups after telomerization of the thiol with the vinyl ether.Cotelomerization is similar, but we have also shown that the transfer activity of the thiols on all radical species bearing a vinyl ether end is very important and leads almost solely to monoadditions consuming large quantities of thiol.We deduce therefore, that in these reactions, we obtain mixtures of copolymers (formed after total consumption of the thiol) and of these adducts having a low molecular weight.
