Check Digit Verification of cas no

The CAS Registry Mumber 83641-05-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,6,4 and 1 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 83641-05:
(7*8)+(6*3)+(5*6)+(4*4)+(3*1)+(2*0)+(1*5)=128
128 % 10 = 8
So 83641-05-8 is a valid CAS Registry Number.

Oxa-Pictet-Spengler reaction in water. Synthesis of some (±)-1-aryl-6,7-dimethoxyisochromans

Saeed, Aamer

experimental part, p. 261 - 264 (2010/11/19)

An acid catalyzed oxa-Pictet-Spengler reaction 'on water' leading to the synthesis of a variety of 1-aryl-6,7-dimethoxyisochromans is described. The aqueous chemistry is a much cleaner, efficient, cheaper and simple method for synthesis. The scope of reac
