Check Digit Verification of cas no

The CAS Registry Mumber 128965-40-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,9,6 and 5 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 128965-40:
(8*1)+(7*2)+(6*8)+(5*9)+(4*6)+(3*5)+(2*4)+(1*0)=162
162 % 10 = 2
So 128965-40-2 is a valid CAS Registry Number.

THE PICTET-SPENGLER REACTION OF Nb-HYDROXYTRYPTAMINES AND CYSTEINALS. I. ISOLATION OF TETRACYCLIC INTERMEDIATES AND FORMATION OF OPTICALLY ACTIVE Nb-HYDROXY-TETRAHYDRO-β-CARBOLINES

Liu, Jinjun,Nakagawa, Masako,Hino, Tohru

, p. 7729 - 7742 (2007/10/02)

The Pictet-Spengler(P-S) reaction of Nb-hydroxytryptamines 5 and cysteinals 6 in the presence of trifluoroacetic acid(TFA) at room temperature gave the tetracyclic compounds 7α as well as the corresponding Nb-hydroxy-β-carbolines 8.The optically active nitrones 9, isolated from the similar reaction of 5 and optically active 6, gave optically active 7α and 8.
