Check Digit Verification of cas no

The CAS Registry Mumber 204515-22-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,4,5,1 and 5 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 204515-22:
(8*2)+(7*0)+(6*4)+(5*5)+(4*1)+(3*5)+(2*2)+(1*2)=90
90 % 10 = 0
So 204515-22-0 is a valid CAS Registry Number.

, p. 653 - 654 (1999)

An economical synthesis of famciclovir from N-2-acetyl-7-benzylguanine by a novel regioselective alkylation with the diester cyclopropane compound was developed.

Improved industrial syntheses of penciclovir and famciclovir using N2-acetyl-7-benzylguanine and a cyclic side chain precursor

Torii, Takayoshi,Yamashita, Keizo,Kojima, Mitsuhiko,Suzuki, Yumiko,Hijiya, Toyoto,Izawa, Kunisuke

, p. 625 - 634 (2006)

We have established practical synthetic methods for penciclovir (PCV, 1) and famciclovir (FCV, 2) from N2-acetyl-7-benzylguanine (NAc7BnG, 3) and 6,6-dimethyl-5,7-dioxaspiro[2.5]octane-4,8-dione (4)-the latter being a more easily prepared cyclic precursor
