Check Digit Verification of cas no
The CAS Registry Mumber 40925-61-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,9,2 and 5 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 40925-61:
(7*4)+(6*0)+(5*9)+(4*2)+(3*5)+(2*6)+(1*1)=109
109 % 10 = 9
So 40925-61-9 is a valid CAS Registry Number.

The lithium bromide mediated condensation of 1-amino-2-heteroaryl substrates with ethyl cyanoformate, to obtain versatile alkylcarbamate protected benzoheteroazolones was studied. This unprecedented reaction could be used to furnish different azolones like 2-benzimidazolones, 2-benooxazolones and 2-amino-thiazoles in good yields. 2011 Bentham Science Publishers Ltd.
