Check Digit Verification of cas no
The CAS Registry Mumber 157336-56-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,7,3,3 and 6 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 157336-56:
(8*1)+(7*5)+(6*7)+(5*3)+(4*3)+(3*6)+(2*5)+(1*6)=146
146 % 10 = 6
So 157336-56-6 is a valid CAS Registry Number.

An improved procedure for the synthesis of fluoromethylketones: Flash vacuum pyrolytic elimination
Reutrakul, Vichai,Kruahong, Thongchai,Pohmaktor, Manat
, p. 4851 - 4852 (2007/10/02)
Fluoromethylketones 3 are synthesized in good yields by a flash vacuum pyrolytic elimination of 2. Studies on the improved synthesis of 2 leads to the evidence on the existence of α,α-dilithio fluoromethyl phenyl sulfoxide.
