Check Digit Verification of cas no

The CAS Registry Mumber 119137-01-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,9,1,3 and 7 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 119137-01:
(8*1)+(7*1)+(6*9)+(5*1)+(4*3)+(3*7)+(2*0)+(1*1)=108
108 % 10 = 8
So 119137-01-8 is a valid CAS Registry Number.

PHOTOACTIVABLE FLUOROPHORES. 1. SYNTHESIS AND PHOTOACTIVATION OF o-NITROBENZYL-QUENCHED FLUORESCENT CARBAMATES

Cummings, Richard T,Krafft, Grant A.

, p. 65 - 68 (2007/10/02)

The synthesis and photoactivation of a new type of fluorescent probe, the photoactivable fluorophore (PAF) are described.The PAFs described in this paper consist of fluorescent aromatic amines coupled to substituted nitrobenzyl quenching chromophores via a carbamate linkage.Photoactivation occurs by an intramolecular photo-redox reaction, converting the o-nitrosobenzaldehyde hemiacetal which fragments with loss of CO2 to liberate the fluorescent amine.Photoactivation quantum yields also are reported.
