119216-53-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 119216-53-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,9,2,1 and 6 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 119216-53:
(8*1)+(7*1)+(6*9)+(5*2)+(4*1)+(3*6)+(2*5)+(1*3)=114
114 % 10 = 4
So 119216-53-4 is a valid CAS Registry Number.

SYNTHESIS OF 3-PYRROLINES VIA A -ANNULATION STRATEGY
Padwa, Albert,Norman, Bryan H.
, p. 3041 - 3044 (2007/10/02)
The reaction of amines with 2,3-diphenylsulfonyl-1,3-butadiene produces 3-pyrrolines which are readily oxidized to 3-phenylsulfonyl pyrroles.
