135350-33-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 135350-33-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,5,3,5 and 0 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 135350-33:
(8*1)+(7*3)+(6*5)+(5*3)+(4*5)+(3*0)+(2*3)+(1*3)=103
103 % 10 = 3
So 135350-33-3 is a valid CAS Registry Number.

Studies on pyrrolidinones. A new rearrangement of pyrrolo[1,2-b]isoquinolines derivatives
Rigo,Barbry,Couturier
, p. 741 - 747 (2007/10/02)
New lactones are obtained as by-products during the Friedel-Crafts cyclization of N-arylmethyl pyroglutamoyl chlorides. A mechanism based on N-acyliminium salts is proposed to explain their formation.
