33210-00-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 33210-00-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,2,1 and 0 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 33210-00:
(7*3)+(6*3)+(5*2)+(4*1)+(3*0)+(2*0)+(1*0)=53
53 % 10 = 3
So 33210-00-3 is a valid CAS Registry Number.

N-p-Toluenesulfonylpyrroles from 1,3-dienes
Harrington,Sanchez
, p. 175 - 180 (2007/10/02)
1,3-Dienes can be converted to N-p-toluenesulfonylpyrroles in two steps: 1) [4+2]-cycloaddition with N-sulfinyl-p-toluenesulfonamide and 2) conversion of the 3,6-dihydro-1,2-thiazine oxide adduct to a pyrrole using triethylamine-trimethylphosphite.
