56071-60-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 56071-60-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,6,0,7 and 1 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 56071-60:
(7*5)+(6*6)+(5*0)+(4*7)+(3*1)+(2*6)+(1*0)=114
114 % 10 = 4
So 56071-60-4 is a valid CAS Registry Number.

Cross-dehydrogenative coupling between enamino esters and ketones: Synthesis of tetrasubstituted pyrroles
Zhao, Miao,Wang, Fen,Li, Xingwei
, p. 1412 - 1415 (2012/05/04)
Tetrasubstituted pyrroles have been synthesized via the cross-dehydrogenative coupling between enamino esters and acetone. Silver carbonate proved to be an effective oxidant, and no transition metal catalyst is necessary.
