Check Digit Verification of cas no

The CAS Registry Mumber 499-45-6 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,9 and 9 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 499-45:
(5*4)+(4*9)+(3*9)+(2*4)+(1*5)=96
96 % 10 = 6
So 499-45-6 is a valid CAS Registry Number.

Configuration of Alanine Part in Natural Octopine

Goto, Kazuo,Waki, Michinori,Mitsuyasu, Nobuo,Kitajima, Yasuo,Izumija, Nobuo

, p. 261 - 265 (2007/10/02)

Octopine has a structure of N2-(1-carboxyethyl)arginine or N-(1-carboxy-4-guanidinobutyl)alanine.Configuration of the arginine part in natural octopine is determined as (S), whereas that of the alanine part has been assumed as (R).The configuration of the alanine part was concluded to be (R) by the present synthesis of (+)-octopine, which was identical with the natural one, by a sequence of reactions starting from (R)-alanine and (R)-2-bromo-5-acetamidopentanoic acid.The reaction of (R)-alanine and (R)-2-bromo-5-acetamidopentanoic acid in alkaline conditions gave N2--N5-acetyl-(S)-ornithine which was converted to N2--(S)-ornithine by hydrolysis with hydrochloric acid. (R),(S)-Octopinic acid gave (+)-octopine by guanidination.The reaction of (S)-alanine and (R)-2-bromo-5-acetamidopentanoic acid led to give (S),(S)-octopinic acid and subsequently (+)-isooctopine .
