Check Digit Verification of cas no

The CAS Registry Mumber 1310489-89-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,1,0,4,8 and 9 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1310489-89:
(9*1)+(8*3)+(7*1)+(6*0)+(5*4)+(4*8)+(3*9)+(2*8)+(1*9)=144
144 % 10 = 4
So 1310489-89-4 is a valid CAS Registry Number.

New efficient synthesis of 2,3,4-trisubstituted 3,4-dihydroquinazolines by a Ugi 4CC/Staudinger/aza-Wittig sequence

Zhong, Ying,Wang, Long,Ding, Ming-Wu

, p. 3714 - 3723 (2011/06/21)

A series of 2,3,4-trisubstituted 3,4-dihydroquinazoline 3 was prepared by intramolecular aza-Wittig reaction of amide carbonyl groups with methyldiphenyl iminophosphorane, which was obtained from a Ugi 4CC/Staudinger sequence. Further intramolecular Heck
