Check Digit Verification of cas no

The CAS Registry Mumber 1453125-13-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,5,3,1,2 and 5 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1453125-13:
(9*1)+(8*4)+(7*5)+(6*3)+(5*1)+(4*2)+(3*5)+(2*1)+(1*3)=127
127 % 10 = 7
So 1453125-13-7 is a valid CAS Registry Number.

A one-pot, three-component, microwave-promoted synthesis of 2-amino-substituted 7-amino-1,2,4-triazolo[1,5-a][1,3,5]triazines

Kalinina, Svetlana A.,Kalinin, Dmitrii V.,Dolzhenko, Anton V.

, p. 5537 - 5540 (2013/09/23)

A new, efficient, catalyst-free, one-pot, three-component method for the synthesis of 2-amino-substituted 7-amino-1,2,4-triazolo[1,5-a][1,3,5]triazines using 3,5-diamino-1,2,4-triazoles, cyanamide, and triethyl orthoformate is developed. The reaction proceeds smoothly under microwave-assisted heating. Advantages of the method include using easily available reagents, short reaction times, and operational simplicity.
