Check Digit Verification of cas no

The CAS Registry Mumber 1138457-33-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,3,8,4,5 and 7 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1138457-33:
(9*1)+(8*1)+(7*3)+(6*8)+(5*4)+(4*5)+(3*7)+(2*3)+(1*3)=156
156 % 10 = 6
So 1138457-33-6 is a valid CAS Registry Number.

experimental part, p. 285 - 290 (2009/06/21)

Fully acetylated dodecyl thioglycosides were found to be useful as glycosyl donors by activation with 1-benzenesulfinyl piperidine (BSP) and triflic anhydride (Tf2O) at -78 °C. The glycosyl acceptor was added to the reaction mixture at the same
