Check Digit Verification of cas no

The CAS Registry Mumber 120296-17-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,0,2,9 and 6 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 120296-17:
(8*1)+(7*2)+(6*0)+(5*2)+(4*9)+(3*6)+(2*1)+(1*7)=95
95 % 10 = 5
So 120296-17-5 is a valid CAS Registry Number.

The Pictet-Spengler reaction of N(b)-hydroxytryptamines and cysteinals. II. Temperature effects, stereochemistry and mechanism

Liu,Nakagawa,Ogata,Hino

, p. 1672 - 1676 (2007/10/02)

The effect of temperature on the Pictet-Spengler reaction of N(b)-hydroxytryptamines (1) and cysteinals (2) has been examined. The optically active nitrones (3), obtained from 1 and 2, gave the corresponding N(b)-hydroxy-β-carbolines (4α and 4β) exclusively at -78°C in the presence of an excess of trifluoroacetic acid. The mechanism is discussed in relation to the stereochemistry.
