1233749-68-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1233749-68-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,3,7,4 and 9 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1233749-68:
(9*1)+(8*2)+(7*3)+(6*3)+(5*7)+(4*4)+(3*9)+(2*6)+(1*8)=162
162 % 10 = 2
So 1233749-68-2 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
