Check Digit Verification of cas no
The CAS Registry Mumber 116233-79-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,6,2,3 and 3 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 116233-79:
(8*1)+(7*1)+(6*6)+(5*2)+(4*3)+(3*3)+(2*7)+(1*9)=105
105 % 10 = 5
So 116233-79-5 is a valid CAS Registry Number.

Reaction of Thioaldehydes with 5-Alkoxyoxazoles: A Route to 3-Thiazolines
Vedejs, E.,Fields, S.
, p. 4663 - 4667 (1988)
Generation of thioaldehydes 4 by photolysis of 15 or by thermolysis of 9 in the presence of oxazoles 2 or 3 affords 7 or 8, respectively.Thermally generated thioacetone reacts similarly to give 16 and 17.A mechanism involving an unstable Diels-Alder adduct 5 is most likely.
