Check Digit Verification of cas no
The CAS Registry Mumber 196109-16-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,6,1,0 and 9 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 196109-16:
(8*1)+(7*9)+(6*6)+(5*1)+(4*0)+(3*9)+(2*1)+(1*6)=147
147 % 10 = 7
So 196109-16-7 is a valid CAS Registry Number.

Novel degradable polymer networks containing acetal components
Sui, Xince,Shi, Yan,Fu, Zhifeng
, p. 419 - 425 (2011)
A novel copolymer network with acetal structure was prepared using bis[4-(vinyloxy)butyl] (4-methyl-1,3-phenylene)biscarbamate (BECT) as the crosslinking agent. Firstly, a tri-copolymer of maleic anhydride (MAn), n-butyl vinyl ether (BVE) and 4-hydroxybut
