1251936-30-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1251936-30-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,1,9,3 and 6 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1251936-30:
(9*1)+(8*2)+(7*5)+(6*1)+(5*9)+(4*3)+(3*6)+(2*3)+(1*0)=147
147 % 10 = 7
So 1251936-30-7 is a valid CAS Registry Number.

, p. 515 - 531 (2010)
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
