Check Digit Verification of cas no

The CAS Registry Mumber 352212-99-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,5,2,2,1 and 2 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 352212-99:
(8*3)+(7*5)+(6*2)+(5*2)+(4*1)+(3*2)+(2*9)+(1*9)=118
118 % 10 = 8
So 352212-99-8 is a valid CAS Registry Number.

Reaction of acylpyruvic acid esters with hydrazides

Pakal'Nis,Zerova,Yakimovich,Alekseyev

, p. 408 - 416 (2013/07/26)

Hydrazides reacted with acylpyruvic acid esters possessing a terminal straight chain alkyl substituent at the C=O bond distal from the ester group, giving 5-hydroxy-2-pyrazolines. Acylpyruvates with bulky terminal substituents underwent condensation at the C=O bond adjacent to the ester group, giving products with hydrazone or 5-hydroxy-2-pyrazoline structure and capable of displaying ring-chain equilibrium between these tautomers in solution.
