Check Digit Verification of cas no

The CAS Registry Mumber 91815-85-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,8,1 and 5 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 91815-85:
(7*9)+(6*1)+(5*8)+(4*1)+(3*5)+(2*8)+(1*5)=149
149 % 10 = 9
So 91815-85-9 is a valid CAS Registry Number.

The Reformatski Reaction of 1-Aryl-2(1H)-pyrimidinones

Katoh, Akira,Omote, Yoshimori,Kashima, Choji

, p. 53 - 55 (2007/10/02)

1-Aryl-2-(1H)-pyrimidinones I reacted with α-haloesters in the presence of zinc to give mainly 3,4-dihydro-4-alkoxycarbonylmethyl-1-aryl-2(1H)-pyrimidinones IV in addition to the minor products of 3,6-dihydro-6-alkoxycarbonylmethyl-1-aryl-2(1H)-pyrimidinones V.Further, 3,4-dihydro derivatives IVa-c were successfully converted into the corresponding exomethylene compounds VIa-c in high yields.
