Check Digit Verification of cas no

The CAS Registry Mumber 1198794-75-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,9,8,7,9 and 4 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1198794-75:
(9*1)+(8*1)+(7*9)+(6*8)+(5*7)+(4*9)+(3*4)+(2*7)+(1*5)=230
230 % 10 = 0
So 1198794-75-0 is a valid CAS Registry Number.

experimental part, p. 9200 - 9208 (2011/09/19)

β-Substituted α-fluoro-α,β-unsaturated carboxylic acids have been successfully synthesized, usually in a (Z)-stereospecific manner by way of a stepwise or a one-pot three-step procedure starting from 2-chloro-1,1,1,2-tetrafluoroethane (HCFC-124), one of the major byproducts of the industrial process for tetrafluoroethene formation from chlorofluoromethane (HCFC-22). Get some Z's! β-Substituted α-fluoro-α,β- unsaturated carboxylic acids have been successfully synthesized from 2-chloro-1,1,1,2-tetrafluoroethane, one of the major byproducts of tetrafluoroethene formation from chlorofluoromethane. The products are usually obtained with Z stereoselectivity, by either a stepwise or a one-pot three-step procedure (see scheme).
