Check Digit Verification of cas no

The CAS Registry Mumber 52989-48-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,2,9,8 and 9 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 52989-48:
(7*5)+(6*2)+(5*9)+(4*8)+(3*9)+(2*4)+(1*8)=167
167 % 10 = 7
So 52989-48-7 is a valid CAS Registry Number.

Synthesis of functionalized dihydrothiophenes from doubly activated cyclopropanes using tetrathiomolybdate as the sulfur transfer reagent

Gopinath, Purushothaman,Chandrasekaran, Srinivasan

supporting information; experimental part, p. 700 - 703 (2011/03/20)

A number of doubly activated cyclopropanes were synthesized starting from various substituted bromosulfonium bromides in good yield. Regioselective ring-opening of cyclopropanes with tetrathiomolybdate as the sulfur transfer reagent gave dihydrothiophenes
