Check Digit Verification of cas no

The CAS Registry Mumber 881011-20-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,8,1,0,1 and 1 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 881011-20:
(8*8)+(7*8)+(6*1)+(5*0)+(4*1)+(3*1)+(2*2)+(1*0)=137
137 % 10 = 7
So 881011-20-7 is a valid CAS Registry Number.

RADICALLY POLYMERIZABLE SULFUR-CONTAINING COMPOUND AND RADICALLY POLYMERIZABLE SULFUR-CONTAINING POLYMER

-

Page/Page column 46-47, (2008/06/13)

The invention relates to a radically polymerizable sulfur-containing compound having a group represented by formula (1) and at least one selected from among groups represented by formulae (2) to (4) , a radically polymerizable sulfur-containing polymer obtained by subjecting the compound to cationic ring-opening (co)polymerization, production process thereof, a composition containing the sulfur-containing compound and/or the sulfur-containing polymer, and a cured product obtained from the composition……………. (1)(2) (3) (4)………….( R1 to R6 each independently represents a hydrogen atom or an alkyl group having 1 to 4 carbon atoms.) The cured product obtained from the radically polymerizable sulfur-containing compound and the radically polymerizable sulfur-containing polymer having a high refractive index is useful as an optical material, especially for lens material.
