Check Digit Verification of cas no
The CAS Registry Mumber 133535-76-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,5,3 and 5 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 133535-76:
(8*1)+(7*3)+(6*3)+(5*5)+(4*3)+(3*5)+(2*7)+(1*6)=119
119 % 10 = 9
So 133535-76-9 is a valid CAS Registry Number.

Efficient acylation of alcohols with acylthiazolidine-2-thiones and cesium fluoride
Yamada, M.,Yahiro, S.,Yamano, T.,Nakatani, Y.,Ourisson, G.
, p. 824 - 829 (2007/10/02)
Primary alcohols are acylated in good yield under almost neutral conditions with 3-acylthiazolidine-2-thiones and cesium fluoride.For secondary alcohols, the yield is improved by the addition of zinc bromide. t-Butanol is not acylated.
