17136-85-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 17136-85-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,1,3 and 6 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 17136-85:
(7*1)+(6*7)+(5*1)+(4*3)+(3*6)+(2*8)+(1*5)=105
105 % 10 = 5
So 17136-85-5 is a valid CAS Registry Number.

A versatile synthesis of 3-phenylsulfonylpyrroles from α-amino acids
Burley,Hewson
, p. 1151 - 1154 (2007/10/02)
Reaction between α-benzamidoalkyl ketones 4a-e and the vinyl phosphonium salt 1 produces 3-phenylthio-3-pyrrolines 5a-e which can be converted into N-benzyl-3-phenylsulfonyl pyrroles 7a-e by m-CPBA oxidation, diborane reduction and DDQ aromatisation.
