Check Digit Verification of cas no

The CAS Registry Mumber 1606994-77-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,0,6,9,9 and 4 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1606994-77:
(9*1)+(8*6)+(7*0)+(6*6)+(5*9)+(4*9)+(3*4)+(2*7)+(1*7)=207
207 % 10 = 7
So 1606994-77-7 is a valid CAS Registry Number.

Tandem Phospha-Michael Addition/N-Acylation/ Intramolecular Wittig Reaction of aza-o-Quinone Methides: Approaches to 2,3-Disubstituted Indoles

Hua, Ting-Bi,Chao, Fei,Wang, Long,Yan, Chen-Yang,Xiao, Cong,Yang, Qing-Qing,Xiao, Wen-Jing

supporting information, p. 2615 - 2619 (2020/05/18)

A tandem phospha-Michael addition/N-acylation/intramolecular Wittig reaction of in situ formed aza-o-QMs is disclosed. This approach features high functional group tolerance and provides a convenient and practical access to biologically significant indole derivatives (37 examples, up to 91% yield) under mild reaction conditions. (Figure presented.).
