135273-33-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 135273-33-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,5,2,7 and 3 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 135273-33:
(8*1)+(7*3)+(6*5)+(5*2)+(4*7)+(3*3)+(2*3)+(1*3)=115
115 % 10 = 5
So 135273-33-5 is a valid CAS Registry Number.

New experiments in the reductive N-alkylation and N-peralkylation of aromatic amines
Verardo,Giumanini,Strazzolini
, p. 609 - 627 (1994)
Some secondary and primary aromatic amines were variously N-alkylated and N-peralkylated by the aldehyde-sodium borohydride procedure in acidic aqueous solution. The procedure lends itself to the α-mono and α,α1-dideuterium labelling of the new N-substituent(s).
