Check Digit Verification of cas no

The CAS Registry Mumber 1428250-75-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,8,2,5 and 0 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1428250-75:
(9*1)+(8*4)+(7*2)+(6*8)+(5*2)+(4*5)+(3*0)+(2*7)+(1*5)=152
152 % 10 = 2
So 1428250-75-2 is a valid CAS Registry Number.

A facile synthesis of 3,5,7-trisubstituted-4H-[1,2]diazepines by microwave irradiation

Manih, Rudolf Manton,Myrboh, Bekington

, p. 1613 - 1618 (2013/01/15)

A novel approach for the synthesis of 3,5,7-trisubstituted-4H-[1,2] diazepine 5a-p from α,β-unsaturated 1,5-diketone 4 by the condensation of substituted acetophenones 1 with 1,3-dicarbonyl compound 3 in the presence of sodium tertiary butoxide has been described. The intermediate 4 reacts smoothly with hydrazine hydrate catalysed by PSSA in water under microwave irradiation to yield the product 5.
