Check Digit Verification of cas no
The CAS Registry Mumber 949020-60-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,4,9,0,2 and 0 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 949020-60:
(8*9)+(7*4)+(6*9)+(5*0)+(4*2)+(3*0)+(2*6)+(1*0)=174
174 % 10 = 4
So 949020-60-4 is a valid CAS Registry Number.

Vilsmeier-Haak formylation of 3,5-dimethylpyrazoles
Attaryan,Antanosyan,Panosyan,Asratyan,Matsoyan
, p. 1817 - 1819 (2008/02/08)
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.
