127271-22-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 127271-22-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,2,7 and 1 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 127271-22:
(8*1)+(7*2)+(6*7)+(5*2)+(4*7)+(3*1)+(2*2)+(1*2)=111
111 % 10 = 1
So 127271-22-1 is a valid CAS Registry Number.

Synthesis of β-Lactams from Novel Stannous Enolates and Imines
Sugano, Yuichi,Naruto, Shunji
, p. 1331 - 1334 (2007/10/02)
From the oxygen esters containing sulfur α-substituent, corresponding stannous enolates were prepared by the use of stannous trifluoromethanesulfonate.The enolates reacted with various imines to provide β-lactams.
