91544-38-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 91544-38-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,5,4 and 4 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 91544-38:
(7*9)+(6*1)+(5*5)+(4*4)+(3*4)+(2*3)+(1*8)=136
136 % 10 = 6
So 91544-38-6 is a valid CAS Registry Number.

Mathew, Paulson,Asokan
, p. 1708 - 1716 (2007/10/03)
α-Oxoketene-N,S-acetals, prepared by the reaction of alkyl glycinate hydrochlorides with β-oxodithiocarboxylates followed by alkylation, underwent cyclization in presence of chloromethyleneiminium salt derived from POCl3/DMF to afford alkyl-3-a
