Check Digit Verification of cas no
The CAS Registry Mumber 960009-36-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,6,0,0,0 and 9 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 960009-36:
(8*9)+(7*6)+(6*0)+(5*0)+(4*0)+(3*9)+(2*3)+(1*6)=153
153 % 10 = 3
So 960009-36-3 is a valid CAS Registry Number.

Synthesis of Sildenafil citrate and process related impurities
Kumar, Indukuri V.S.,Ramanjaneyulu, Gorantla S.,Bindu, Vurimindi H.
, p. 668 - 673 (2011)
Synthesis of Sildenafil by the O-alkylation of 5-[2-hydroxy-5-(4- methylpiperazin-1-ylsulphonyl)phenyl]-1-methyl-3-n-propyl-1,6-dihydro-7H- pyrazolo-[4,3-d]pyrimidin-7-one 8 proved difficult because concomitant alkylation of the pyrimidine moity also occurred. The selective O-alkylation was carried by DCC assisted decarboxilative etherification of the carbonate 9.
