Check Digit Verification of cas no

The CAS Registry Mumber 1173901-24-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,7,3,9,0 and 1 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1173901-24:
(9*1)+(8*1)+(7*7)+(6*3)+(5*9)+(4*0)+(3*1)+(2*2)+(1*4)=140
140 % 10 = 0
So 1173901-24-0 is a valid CAS Registry Number.

experimental part, p. 219 - 223 (2010/04/23)

7-amino-2H-indazolo[2, 1-b]phthalazine-1, 6, 11(13H)-triones were synthesized via the three-component condensation of luminol, dimedone, and aromatic aldehydes in EtOH at 80 °C for 9-15 min catalyzed by solid silica sulfuric acid (SSA) and the luminescenc
