Check Digit Verification of cas no
The CAS Registry Mumber 20062-41-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,0,6 and 2 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 20062-41:
(7*2)+(6*0)+(5*0)+(4*6)+(3*2)+(2*4)+(1*1)=53
53 % 10 = 3
So 20062-41-3 is a valid CAS Registry Number.

Reaction of 1-(5-hydroxy-3-methyl-1-substituted-4-pyrazolyl)-1,3-butanediones (1a-d) with 1-hydrazinophthalazine hydrochloride leads to the formation of 4-acetyl-5-hydroxy-3-methyl-1-substituted pyrazoles (3a-d) along with 3-methyl-s-triazolo[3,4-a]phthalazine (4) in good yields.
