1245918-24-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1245918-24-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,5,9,1 and 8 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1245918-24:
(9*1)+(8*2)+(7*4)+(6*5)+(5*9)+(4*1)+(3*8)+(2*2)+(1*4)=164
164 % 10 = 4
So 1245918-24-4 is a valid CAS Registry Number.

Synthesis of some new mono- and bis-polycyclic aromatic spiro and bis-nonspiro-β-lactams
Jarrahpour, Aliasghar,Ebrahimi, Edris
experimental part, p. 515 - 531 (2010/05/02)
Some new mono-and bis-polycyclic aromatic spiro-β-lactams and bis-non spiropolycyclic aromatic β-lactams have been synthesized from imines derived from anthracene-9-carbaldehyde, 2-naphtaldehyde and a ketene derived from 9H-xanthene-9carboxylic acid and p
