Check Digit Verification of cas no
The CAS Registry Mumber 114936-20-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,4,9,3 and 6 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 114936-20:
(8*1)+(7*1)+(6*4)+(5*9)+(4*3)+(3*6)+(2*2)+(1*0)=118
118 % 10 = 8
So 114936-20-8 is a valid CAS Registry Number.

Reactions between aminopyrazole-4-carboxylic acids derivatives and orthoesters or amide acetals lead, in most cases, to the introduction of a heteroalkylidene moiety on the amino group of ethyl aminopyrazole-4-carboxylates and on the β-hydrazide nitrogen atom of aminopyrazole-4-carboxhydrazides. Several factors governing the course of these reactions are discussed.
