Check Digit Verification of cas no

The CAS Registry Mumber 210407-20-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,0,4,0 and 7 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 210407-20:
(8*2)+(7*1)+(6*0)+(5*4)+(4*0)+(3*7)+(2*2)+(1*0)=68
68 % 10 = 8
So 210407-20-8 is a valid CAS Registry Number.

supporting information, p. 4295 - 4299 (2014/06/23)

In this study, a facile CuI catalyzed synthesis of sulfones involving a nucleophilic addition of functionalized organozinc reagents to organic sulfonyl chlorides is realized. This reaction proceeds efficiently at room temperature, giving rise to various functional group substituted sulfones, generally in moderate to high yields. The method provides a novel, simple, and promising strategy for functionalized sulfone synthesis in the research field of sulfur chemistry. the Partner Organisations 2014.
