Check Digit Verification of cas no

The CAS Registry Mumber 643745-03-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,4,3,7,4 and 5 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 643745-03:
(8*6)+(7*4)+(6*3)+(5*7)+(4*4)+(3*5)+(2*0)+(1*3)=163
163 % 10 = 3
So 643745-03-3 is a valid CAS Registry Number.

Environmentally friendly and efficient: Iron-mediated reduction of 3-methyl-5-aryl-1,2,4-oxadiazoles to benzamidines

Sendzik, Martin,Hui, Hon C.

, p. 8697 - 8700 (2007/10/03)

A new synthetic method is described for the mild and selective reduction of 3-methyl-5-aryl-1,2,4-oxadiazoles to amidines employing iron powder in aqueous medium. Its application is demonstrated in the synthesis of 1, a potent and selective urokinase-type plasminogen activator (uPA) inhibitor.
