Check Digit Verification of cas no

The CAS Registry Mumber 1210820-74-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,1,0,8,2 and 0 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1210820-74:
(9*1)+(8*2)+(7*1)+(6*0)+(5*8)+(4*2)+(3*0)+(2*7)+(1*4)=98
98 % 10 = 8
So 1210820-74-8 is a valid CAS Registry Number.

Substituent effects on the electron transfer-initiated photochemical transformation of 1,2,4-triazole-substituted α-dehydroarylalaninamides into 2(1H)-quinolinone derivatives

Yazawa, Yuichi,Suzuki, Minoru,Igarashi, Tetsutaro,Sakurai, Tadamitsu

experimental part, p. 199 - 206 (2010/05/18)

An investigation was undertaken to elucidate substituent effects on the photoreactivity of 1,2,4-triazole-substituted α-dehydroarylalaninamides [(Z)-1] as well as on the selectivity of 2(1H)-quinolinone derivatives (2) from a synthetic point of view. It was found that photoinduced electron transfer-initiated cyclization of (Z)-1 bearing a meta-substituted phenyl or a 4-substituted naphthalen-1-yl group in methanol proceeds with a moderate to good efficiency affording the corresponding product 2 in a selectivity ranging from 33 to 100%.
