Check Digit Verification of cas no
The CAS Registry Mumber 162221-28-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,2,2,2 and 1 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 162221-28:
(8*1)+(7*6)+(6*2)+(5*2)+(4*2)+(3*1)+(2*2)+(1*8)=95
95 % 10 = 5
So 162221-28-5 is a valid CAS Registry Number.

, p. 532 - 537 (2007/10/03)
The task of process research, namely developing efficient, economically and technically as well as ecologically feasible syntheses in time, is demonstrated on the HIV-proteinase inhibitor Saquinavir (1), a complex molecule comprising six stereo-centres. Based on the first 26-step research synthesis furnishing a 10% overall yield, process research established a new, short 11-step synthesis affording a 50% overall yield.
