Check Digit Verification of cas no

The CAS Registry Mumber 1248635-19-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,8,6,3 and 5 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1248635-19:
(9*1)+(8*2)+(7*4)+(6*8)+(5*6)+(4*3)+(3*5)+(2*1)+(1*9)=169
169 % 10 = 9
So 1248635-19-9 is a valid CAS Registry Number.

New efficient synthesis of pyrimido[1,6-c]quinazolin-4-ones by a Biginelli 3CC/Staudinger/aza-Wittig sequence

Li, Wen-Jing,Liu, Shuai,He, Ping,Ding, Ming-Wu

experimental part, p. 8151 - 8159 (2010/10/21)

Dihydropyrimidinone azides 1, obtained from trimethylsilyl chloride-catalyzed Biginelli reaction of 2-azidobenzaldehyde, ethyl acetoacetate, and urea (or thiourea) at room temperature, reacted with triphenylphosphine to give iminophosphorane 2. A tandem aza-Wittig reaction of iminophosphorane 2 with isocyanate, acyl chloride or CS2 in the presence of K2CO3 or NEt3 generated pyrimido[1,6-c]quinazolin-4-ones 4, 6 or 8 in moderate to good yield.
