Check Digit Verification of cas no

The CAS Registry Mumber 219697-18-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,9,6,9 and 7 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 219697-18:
(8*2)+(7*1)+(6*9)+(5*6)+(4*9)+(3*7)+(2*1)+(1*8)=174
174 % 10 = 4
So 219697-18-4 is a valid CAS Registry Number.

Synthesis of 4-(Meth)acrylamido-4-methylsulfolane-3-sulfonic Acid

Kazakov, S. A.,Kazantsev, O. A.,Shirshin, K. V.,Danov, S. M.

, p. 1233 - 1235 (2007/10/03)

A new acrylamide monomer containing a sulfo group and a sulfolane moiety was prepared by reaction of (meth)acrylonitrile with 3-methyl-3-sulfolene and a sulfonating agent (oleum or 98-100 percent sulfuric acid) under mild conditions. The synthesis conditions were optimized to ensure a high yield of the target product.
