Check Digit Verification of cas no

The CAS Registry Mumber 3514-11-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,5,1 and 4 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 3514-11:
(6*3)+(5*5)+(4*1)+(3*4)+(2*1)+(1*1)=62
62 % 10 = 2
So 3514-11-2 is a valid CAS Registry Number.

1,2,3-Triazines, V1: Lithiation of 1,2,3-triazines

Bau, Bernarde,Hofmann, Thorsten,Kloss, Juergen,Neunhoeffer, Hans

, p. 119 - 136 (2007/10/03)

5-Ethoxy-1,2,3-triazine (15) can be mono- and dilithiated and the lithio-1,2,3-triazines (16, 17) were reacted with aldehydes to give 18a-c, 19a-c, 20a-c and 21a-c. 18-21 can be oxidized to give the benzoyl-1,2,3- triazines 22a-c, 23c and 24a-c. Condensation of 24c with hydrazine afforded the pyrazolo[4.3-d]1,2,3-triazine 25 and 24a-c with ethylene diamine afforded the 1,2,3-triazino[5,4-e][1,4]diazepines 27a-c. 4-Methoxy-1,2,3-triazine (12) forms as well the 5- as the 6-lithio-4-methoxy-1,2,3-triazine (28a,b), whose reaction with benzaldehyde gave the 5- and 6-(α-hydroxybenzyl)-4,methoxy- 1,2,3-triazines (29a,b), respectively.
