Check Digit Verification of cas no

The CAS Registry Mumber 1340540-92-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,4,0,5,4 and 0 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1340540-92:
(9*1)+(8*3)+(7*4)+(6*0)+(5*5)+(4*4)+(3*0)+(2*9)+(1*2)=122
122 % 10 = 2
So 1340540-92-2 is a valid CAS Registry Number.

Microwave-assisted synthesis of N1- and C3-substituted pyrazolo[3,4-d] pyrimidine libraries

Todorovic, Nick,Awuah, Emelia,Shakya, Tushar,Wright, Gerard D.,Capretta, Alfredo

, p. 5761 - 5763 (2011/12/03)

The parallel synthesis of a library N1- and C3-substituted-pyrazolo[3,4-d] pyrimidines is described. The microwave-assisted approach involves the de novo generation of the heterocyclic scaffold, facile alkylation at N1 via either a Mitsunobu or a direct alkylation reaction and arylation at C3 via a Suzuki reaction.
