Check Digit Verification of cas no
The CAS Registry Mumber 154120-88-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,4,1,2 and 0 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 154120-88:
(8*1)+(7*5)+(6*4)+(5*1)+(4*2)+(3*0)+(2*8)+(1*8)=104
104 % 10 = 4
So 154120-88-4 is a valid CAS Registry Number.

Khodja, Mohamed,Sicker, Dieter,Wilde, Horst
, p. 401 - 412 (2007/10/02)
3,4-Dihydropyridazinobenzimidazoles (4a-e) have been prepared by catalytical hydrogenation of dialkyl (E)-2-(substituted 2-nitrophenylhydrazono)glutarates (1a-e) to the respective amines (2) followed by their base catalyzed cyclization in a tandem
