Check Digit Verification of cas no

The CAS Registry Mumber 640298-99-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,4,0,2,9 and 8 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 640298-99:
(8*6)+(7*4)+(6*0)+(5*2)+(4*9)+(3*8)+(2*9)+(1*9)=173
173 % 10 = 3
So 640298-99-3 is a valid CAS Registry Number.

Utilization of Cleavage of the [1]Benzofuro[2,3-e][1,2,4]triazine Ring for the Synthesis of Oxygen, Nitrogen and Sulfur Derivatives of [1,2,4]Triazine [1]

Styskala, Jakub,Slouka, Jan,Wiedermannova, Iveta,Bednar, Petr

, p. 805 - 811 (2003)

A series of 6-azacytosines 4a-4k and 5a-5c were prepared by nucleophilic cleavage of furan ring of [1]benzofuro[2,3-e][1,2,4]triazine derivative 1. Some of them were used for the preparation of derivatives of [1,2,4]triazolo[4,3-d][1,2,4]triazine (6a-6d)
