Check Digit Verification of cas no

The CAS Registry Mumber 169139-72-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,9,1,3 and 9 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 169139-72:
(8*1)+(7*6)+(6*9)+(5*1)+(4*3)+(3*9)+(2*7)+(1*2)=164
164 % 10 = 4
So 169139-72-4 is a valid CAS Registry Number.

Synthesis of chiral sulfines by oxidation of dithio esters

Linden, Johannes B. van der,Timmermans, Johan L.,Zwanenburg, Binne

, p. 91 - 96 (2007/10/02)

The synthesis of sulfines (thione oxides) (2, 10 and 17) derived from three chiral dithio esters (1, 8 and 16) bearing a hydrogen at the α-carbon atom is described.The sulfine bearing an amido group at C-α (2), does not racemize and proved to be stable ov
