Check Digit Verification of cas no

The CAS Registry Mumber 1242099-09-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,2,0,9 and 9 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1242099-09:
(9*1)+(8*2)+(7*4)+(6*2)+(5*0)+(4*9)+(3*9)+(2*0)+(1*9)=137
137 % 10 = 7
So 1242099-09-7 is a valid CAS Registry Number.

Crystal engineering of multiple-component organic solids: Pharmaceutical cocrystals of tadalafil with persistent hydrogen bonding motifs

Weyna, David R.,Cheney, Miranda L.,Shan, Ning,Hanna, Mazen,Wojtas, Lukasz,Zaworotko, Michael J.

body text, p. 2377 - 2380 (2012/07/14)

Pharmaceutical cocrystals of tadalafil with methylparaben, propylparaben and hydrocinnamic acid have been prepared and characterized. The crystal packing observed in the three resulting cocrystals reveals that tadalafil molecules form persistent hydrogen-
