Check Digit Verification of cas no

The CAS Registry Mumber 683228-58-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,8,3,2,2 and 8 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 683228-58:
(8*6)+(7*8)+(6*3)+(5*2)+(4*2)+(3*8)+(2*5)+(1*8)=182
182 % 10 = 2
So 683228-58-2 is a valid CAS Registry Number.

Competitive Electron Transfer from the S2 and S1 Excited States of Zinc meso-Tetraphenylporphyrin to a Covalently Bound Pyromellitimide: Dependence on Donor-Acceptor Structure and Solvent

Hayes, Ryan T.,Walsh, Christopher J.,Wasielewski, Michael R.

, p. 2375 - 2381 (2004)

Zinc meso-tetraphenylporphyrin (ZnTPP) is known to have a relatively slow S2 → S1 internal conversion rate, (1-3 ps) -1, so that electron transfer from S2 to a nearby acceptor is possible. We have synthesized tw
