Check Digit Verification of cas no

The CAS Registry Mumber 42596-60-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,2,5,9 and 6 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 42596-60:
(7*4)+(6*2)+(5*5)+(4*9)+(3*6)+(2*6)+(1*0)=131
131 % 10 = 1
So 42596-60-1 is a valid CAS Registry Number.

A new procedure for preparation of carboxylic acid hydrazides

The standard method for preparing carboxylic acid hydrazides is hydrazinolysis of esters in alcoholic solutions. However, when applied to α,β-unsaturated esters, the main product typically is the pyrazolidinone resulting from an undesired Michael-type cyclization. Other alternative methodologies reported for direct preparation of hydrazides from acids are inefficient. We developed an efficient and general process, involving preforming activated esters and/or amides followed by reaction with hydrazine, for the preparation of hydrazides including those of α,β-unsaturated acids. This process gives the desired hydrazides in excellent yield and purity under mild conditions.
