124994-76-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 124994-76-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,4,9,9 and 4 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 124994-76:
(8*1)+(7*2)+(6*4)+(5*9)+(4*9)+(3*4)+(2*7)+(1*6)=159
159 % 10 = 9
So 124994-76-9 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.
