Check Digit Verification of cas no

The CAS Registry Mumber 916248-90-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,1,6,2,4 and 8 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 916248-90:
(8*9)+(7*1)+(6*6)+(5*2)+(4*4)+(3*8)+(2*9)+(1*0)=183
183 % 10 = 3
So 916248-90-3 is a valid CAS Registry Number.

Microwave synthesis of new pyrazolo[3,4-d]pyrimidin-4-ones in solvent-free condition

Davoodnia,Anvari,Tavakoli-Hoseini

experimental part, p. 3683 - 3685 (2012/02/06)

An efficient method for the synthesis of new pyrazolo[3,4-d]pyrimidin-4- ones through heterocyclization reaction of 5-amino-l-phenyl- lH-pyrazole-4-carboxamides with aroyl halides under microwave irradiation in solvent-free condition is described. In comparison with classical conditions the reactions are faster and the yields are higher under microwave irradiation.
