Check Digit Verification of cas no

The CAS Registry Mumber 108681-52-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,8,6,8 and 1 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 108681-52:
(8*1)+(7*0)+(6*8)+(5*6)+(4*8)+(3*1)+(2*5)+(1*2)=133
133 % 10 = 3
So 108681-52-3 is a valid CAS Registry Number.

VINYL SULPHONES DERIVED FROM THIOGLYCOSIDES: SYNTHESIS AND ALKYLATION

Cassidy, Joseph F.,Williams, J. Michael

, p. 4355 - 4358 (1986)

Vinyl sulphones (1-sulfonyl glycals) are formed in good yield by elimination of propanone from 2,3-O-isopropylidene derivatives of D-mannopyranosyl and L-rhamnopyranosyl sulphones.Attempted conjugate addition of carbon nucleophiles to these vinyl sulphones, which are deactivated towards nucleophiles by the ring oxygen atom, was unsuccessful but lithiation followed by methylation yielded the 2-methyl vinyl sulphone derivatives when t-butyl sulphones rather than phenyl sulphones were used.
