Check Digit Verification of cas no

The CAS Registry Mumber 172483-93-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,2,4,8 and 3 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 172483-93:
(8*1)+(7*7)+(6*2)+(5*4)+(4*8)+(3*3)+(2*9)+(1*3)=151
151 % 10 = 1
So 172483-93-1 is a valid CAS Registry Number.

Synthesis of Porphyrin-2,3,12,13- and 2,3,7,8-tetraones: Building Blocks for the Synthesis of Extended Porphyrin Arrays

Crossley, Maxwell J.,Govenlock, Linda J.,Prashar, Jognandan K.

, p. 2379 - 2380 (2007/10/03)

The first synthesis of a porphyrin-2,3,12,13-tetraone and porphyrin-2,3,7,8-tetraones is reported; these compounds are useful compounds for the construction of laterally-extended porphyrin systems as is illustrated by the synthesis of linear and bent tris-porphyrins, 10 and 11, respectively, and the tetrakis-porphyrin 12.
