Check Digit Verification of cas no

The CAS Registry Mumber 74794-41-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,7,9 and 4 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 74794-41:
(7*7)+(6*4)+(5*7)+(4*9)+(3*4)+(2*4)+(1*1)=165
165 % 10 = 5
So 74794-41-5 is a valid CAS Registry Number.

Facile Synthesis of 2,5-Diacylthiophenes. II. The Reaction of Diketo Sulfides with 1,2-Diketones

Miyahara, Yuji,Inazu, Takahiko,Yoshino, Tamotsu

, p. 1187 - 1188 (1980)

The base-catalyzed reaction of diketo sulfides (RCOCH2)2S (R=phenyl, p-tolyl) with biacetyl or benzil have provided high yields of 2,5-diacetyltetrahydrothiophene-3,4-diol derivatives rather than the expected 2,5-diacylthiophenes.The diols have been trans
