Check Digit Verification of cas no
The CAS Registry Mumber 21253-99-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,2,5 and 3 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 21253-99:
(7*2)+(6*1)+(5*2)+(4*5)+(3*3)+(2*9)+(1*9)=86
86 % 10 = 6
So 21253-99-6 is a valid CAS Registry Number.

Efficient and regioselective N-1 alkylation of 4-chloropyrazolo[3,4-d]pyrimidine
Br?ndvang, Morten,Gundersen, Lise-Lotte
, p. 3057 - 3059 (2007/10/03)
Efficient and N-1 selective alkylation of 4-chloropyrazolo[3,4-d]pyrimidine can be achieved when the heterocycle is reacted with alcohols under Mitsunobu conditions. The 1-alkyl-pyrazolo[3,4-d]pyrimidines formed can be functionalized further according to known methods, to give a variety of 1,4-disubstituted pyrazolo[3,4-d]pyrimidines. The first example of a palladium-catalyzed coupling reaction on a 4-halopyrazolo[3,4-d]pyrimidine is described.
