Check Digit Verification of cas no
The CAS Registry Mumber 701911-46-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,0,1,9,1 and 1 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 701911-46:
(8*7)+(7*0)+(6*1)+(5*9)+(4*1)+(3*1)+(2*4)+(1*6)=128
128 % 10 = 8
So 701911-46-8 is a valid CAS Registry Number.

Formylation of N-alkyl-3,5-dimethyl-1H-pyrazoles according to Vilsmeier-Haak led to the formation of the corresponding 4-formyl derivatives. 3,5-Dimethyl-1H-pyrazole having no substituent on the nitrogen atom failed to undergo formylation at the 4 position under analogous conditions. 3,5-Dimethyl-1H-pyrazole-4-carbaldehyde was synthesized by alkaline hydrolysis of methyl β-(4-formyl-3,5-dimethyl-1H-pyrazol-1-yl)propionate and subsequent heating of the acid thus formed.
