Check Digit Verification of cas no

The CAS Registry Mumber 868633-46-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,6,8,6,3 and 3 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 868633-46:
(8*8)+(7*6)+(6*8)+(5*6)+(4*3)+(3*3)+(2*4)+(1*6)=219
219 % 10 = 9
So 868633-46-9 is a valid CAS Registry Number.

A selective synthesis of 2-alkylamino thieno [2,3-d] pyrimidin-4(3H)-ones

Sun, Shao-Fa,Yang, Xu-Hong

, p. 367 - 370 (2008/09/18)

2-Alkylamino-thieno[2,3-d]pyrimidin-4(3H)-ones 6 were synthesized by a selective synthetic method, which includes aza-Wittig reaction of iminophosphorane 3 with aromatic isocynate to give carbodiimide 4 and subsequent reaction of 4 with various aliphatic primary amine in the presence of sodium ethoxide.
