Check Digit Verification of cas no
The CAS Registry Mumber 147726-38-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,7,7,2 and 6 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 147726-38:
(8*1)+(7*4)+(6*7)+(5*7)+(4*2)+(3*6)+(2*3)+(1*8)=153
153 % 10 = 3
So 147726-38-3 is a valid CAS Registry Number.

, p. 245 - 249 (2007/10/02)
The synthesis of acylketene O,S-dialkyl acetals 2a-p and acylketene O-aryl S-alkyl acetals 6a-i is described. The compounds 2a-n are obtained by base-catalyzed alkylation of the respective β-oxo thiono esters 4a-n prepared by alkoxythiocarbonylation of ac
