Check Digit Verification of cas no

The CAS Registry Mumber 730961-09-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,3,0,9,6 and 1 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 730961-09:
(8*7)+(7*3)+(6*0)+(5*9)+(4*6)+(3*1)+(2*0)+(1*9)=158
158 % 10 = 8
So 730961-09-8 is a valid CAS Registry Number.

Synthesis of Normorphans through an Efficient Intramolecular Carbamoylation of Ketones

Diaba, Fa?za,Montiel, Juan A.,Serban, Georgeta,Bonjoch, Josep

supporting information, p. 3860 - 3863 (2015/08/18)

An unexpected C-C bond cleavage was observed in trichloroacetamide-tethered ketones under amine treatment and exploited to develop a new synthesis of normophans from 4-amidocyclohexanones. The reaction involves an unprecedented intramolecular haloform-typ

Six-membered nitrogen ring formation by radical cyclization of trichloroacetamides with enones. A synthetic entry to cis-perhydroisoquinoline- 3,6-diones

Vila, Xavier,Quirante, Josefina,Paloma, Laura,Bonjoch, Josep

, p. 4661 - 4664 (2007/10/03)

Intramolecular reactions between 1-(carbamoyl)dichloromethyl radicals and enones acting as radical acceptors are reported for the first time. The Bu 3SnH promoted 6-exo reaction of trichloroacetamides with enones, avoiding the 1,5-hydrogen transfer, constitutes a new synthetic entry to cis-perhydoisoquinoline-3,6-diones.
