Check Digit Verification of cas no

The CAS Registry Mumber 100990-21-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,0,9,9 and 0 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 100990-21:
(8*1)+(7*0)+(6*0)+(5*9)+(4*9)+(3*0)+(2*2)+(1*1)=94
94 % 10 = 4
So 100990-21-4 is a valid CAS Registry Number.

GENERAL SYNTHESIS OF POLYSUBSTITUTED THIOPHENES FROM DIKETO SULFIDES

Nakayama, Juzo,Machida, Haruki,Saito, Ryuji,Hoshino, Masamatsu

, p. 1983 - 1984 (2007/10/02)

Treatment of diketo sulfides with a low-valent titanium reagent at 0 deg C (in two cases at room temperature) affords 3,4-dihydroxythiolanes in good yields.The acid-catalyzed (p-toluenesulfonic acid) dehydration of the latter compounds leads to the corres
