1020209-10-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1020209-10-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,0,2,0 and 9 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1020209-10:
(9*1)+(8*0)+(7*2)+(6*0)+(5*2)+(4*0)+(3*9)+(2*1)+(1*0)=62
62 % 10 = 2
So 1020209-10-2 is a valid CAS Registry Number.

Facile microwave assisted decarbonylation of 4-formyl group in 5-alkyl amino substituted pyrazoles
Sakya, Subas M.,Abrams, Barbara,Snow, Sheri L.,Rast, Bryson
, p. 2280 - 2282 (2008/09/18)
Facile decarbonylation of the 4-formyl group in 5-alkyl amino pyrazoles was seen when reacted with catalytic p-toluene sulfonic acid in methanol under microwave irradiation to provide parent 4-H pyrazoles in good yields.
