Check Digit Verification of cas no

The CAS Registry Mumber 128814-46-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,8,1 and 4 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 128814-46:
(8*1)+(7*2)+(6*8)+(5*8)+(4*1)+(3*4)+(2*4)+(1*6)=140
140 % 10 = 0
So 128814-46-0 is a valid CAS Registry Number.

A facile synthesis of pyrimidone derivatives and single-crystal characterization of pymetrozine

Wang, Baozhu,Ke, Shaoyong,Kishore, Babu,Xu, Xiaoyong,Zou, Zhuyan,Li, Zhong

, p. 2327 - 2336 (2012)

A facile and efficient synthetic methodology for the preparation of aza-pyrimidone and beno-pyrimidone derivatives is described, in which the triazinone ring and dihydroquinazolin-2(1H)-one was convenient constructed. The structures of all the newly synthesized compounds were characterized by mass, 1H NMR, and infrared spectroscopy. In additional, the crystal of pymetrozine was obtained to find useful information such as configuration and molecular action mechanisms.
