Check Digit Verification of cas no

The CAS Registry Mumber 201008-71-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,1,0,0 and 8 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 201008-71:
(8*2)+(7*0)+(6*1)+(5*0)+(4*0)+(3*8)+(2*7)+(1*1)=61
61 % 10 = 1
So 201008-71-1 is a valid CAS Registry Number.

Vilsmeier-Haak formylation of 3,5-dimethylpyrazoles

Attaryan,Antanosyan,Panosyan,Asratyan,Matsoyan

, p. 1817 - 1819 (2006)

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.
