Check Digit Verification of cas no

The CAS Registry Mumber 107977-90-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,7,9,7 and 7 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 107977-90:
(8*1)+(7*0)+(6*7)+(5*9)+(4*7)+(3*7)+(2*9)+(1*0)=162
162 % 10 = 2
So 107977-90-2 is a valid CAS Registry Number.

STEREOSELECTIVE SYNTHESIS OF POLYOLS PRECURSORS BY ALLYL SULPHINYL ANION ADDITION TO CHIRAL ALKOXY ALDEHYDES

Annunziata, Rita,Cinquini, Mauro,Cozzi, Franco,Raimondi, Laura,Stefanelli, Stefania

, p. 5451 - 5456 (1986)

Tandem condensation of chiral α-alkoxy and α,β-dialkoxy aldehydes with allylic sulphinyl anion, and thiophile promoted desulphurization of the resulting α-substituted allylic sulphoxide afford (E)-5-alkoxy-(or 5,6-dialkoxy)-2-alkene-1,4-diols, advanced polyols precursors, the major stereochemical path occuring via a Felkin-Ahn (non chelation control) mode.
