Check Digit Verification of cas no

The CAS Registry Mumber 77785-18-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,7,8 and 5 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 77785-18:
(7*7)+(6*7)+(5*7)+(4*8)+(3*5)+(2*1)+(1*8)=183
183 % 10 = 3
So 77785-18-3 is a valid CAS Registry Number.

Synthesis of Vinca Alkaloids and Related Compounds, XIII. Syntheses Starting from 2-(Ethoxycarbonyl)tryptamine

Kalaus, Gyoergy,Gyoery, Peter,Kajtar-Peredy, Maria,Radics, Lajos,Szabo, Lajos,Szantay, Csaba

, p. 1476 - 1483 (2007/10/02)

The Pictet-Spengler reaction of 2-(ethoxycarbonyl)tryptamine (1) with aldehyde esters 2 and 3 leads to unexpected products (4a and 9a/10a, resp.).The structures of the new compounds were elucidated by spectroscopic and chemical means.
