Check Digit Verification of cas no

The CAS Registry Mumber 135055-71-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,5,0,5 and 5 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 135055-71:
(8*1)+(7*3)+(6*5)+(5*0)+(4*5)+(3*5)+(2*7)+(1*1)=109
109 % 10 = 9
So 135055-71-9 is a valid CAS Registry Number.

Synthesis of N-benzoylamino-1,2,3,6-tetrahydropyridine derivatives as potential anti-inflammatory agents

Mochona, Bereket,Redda, Kinfe K.

, p. 1383 - 1387 (2008/09/18)

(Chemical Equation Presented) N-Benzoylamino-1,2,3,6-tetrahydropyridines 9a-q were synthesized from 4-substituted pyridines in four steps. Amination of pyridines was carried out to prepare intermediate N-aminopyridinium mesylates using mesytelenesulfonyl hydroxmate (MSH) as aminating agent. N-aminopyridinium mestylates reacted with appropriately substituted acyl chlorides to form N-ylides as stable crystalline solids. Partial reduction of N-ylides with mild reducing agent afforded N-benzoylamino-1,2,3,6-tetrahydropyridines in fair to good yields.
