Check Digit Verification of cas no

The CAS Registry Mumber 643735-27-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,4,3,7,3 and 5 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 643735-27:
(8*6)+(7*4)+(6*3)+(5*7)+(4*3)+(3*5)+(2*2)+(1*7)=167
167 % 10 = 7
So 643735-27-7 is a valid CAS Registry Number.

The surprising nucleophilic addition of aminochlorocarbenes to diethyl acetylenedicarboxylate and to oxalyl chloride: Quinolines and benzo[1,4]diazepines from N-alkylformanilides and oxalyl chloride in the presence of Huenig's base

Cheng, Ying,Yang, Hua,Meth-Cohn, Otto

, p. 3605 - 3610 (2007/10/03)

Vilsmeier reagents derived from N-methylformanilides undergo ready deprotonation with Huenig's base. In xylene, the derived nucleophilic arylaminochlorocarbenes bearing 4-methyl- and 4-methoxy-substituents react with acetylenedicarboxylates to give 2-(2-c
