Check Digit Verification of cas no

The CAS Registry Mumber 199123-05-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,9,1,2 and 3 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 199123-05:
(8*1)+(7*9)+(6*9)+(5*1)+(4*2)+(3*3)+(2*0)+(1*5)=152
152 % 10 = 2
So 199123-05-2 is a valid CAS Registry Number.

New photolabile protecting groups in nucleoside and nucleotide chemistry - Synthesis, cleavage mechanisms and applications

Giegrich,Eisele-Buehler,Hermann,Kvasyuk,Charubala,Pfleiderer

, p. 1987 - 1996 (2007/10/03)

New photolabile protecting groups have been found in the 2-(2- nitrophenyl)ethoxycarbonyl and the 2-(2-nitrophenyl)ethylsulfonyl group, respectively. The influence of substituents at the phenyl ring as well as the side-chain has been investigated regarding the photolysis rates on irradiation at 365 mn. β-Branching in the side-chain leads to highly increased rates of photodeprotection. A new type of photocleavage mechanism consisting of a photoinduced β-elimination process is proposed.
