953781-83-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 953781-83-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,5,3,7,8 and 1 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 953781-83:
(8*9)+(7*5)+(6*3)+(5*7)+(4*8)+(3*1)+(2*8)+(1*3)=214
214 % 10 = 4
So 953781-83-4 is a valid CAS Registry Number.

Diastereoselective synthesis of γ-lactams by a one-pot, four-component reaction
Jingqiang, Wei,Shaw, Jared T.
, p. 4077 - 4080 (2008/02/11)
A new one-pot, four-component reaction (4CR) between amines, maleic anhydrides, aldehydes, and thiols has been discovered to form tetra-and pentasubstituted γ-lactams with high diastereoselectivity. Each component is independently variable and employed in
