Check Digit Verification of cas no

The CAS Registry Mumber 330785-99-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,3,0,7,8 and 5 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 330785-99:
(8*3)+(7*3)+(6*0)+(5*7)+(4*8)+(3*5)+(2*9)+(1*9)=154
154 % 10 = 4
So 330785-99-4 is a valid CAS Registry Number.

, p. 5460 - 5465 (2015/01/08)

Novel pyrimidine-5-carboxamide derivatives bearing a 3-chloro-4-methoxybenzylamino group at the 4-position were identified as potent and highly selective phosphodiesterase 5 inhibitors. Among them, we successfully found 10j (avanafil) which exhibited a potent relaxant effect on isolated rabbit cavernosum (EC30 = 2.1 nM) and a high isozyme selectivity.
