Check Digit Verification of cas no

The CAS Registry Mumber 1245471-34-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,5,4,7 and 1 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1245471-34:
(9*1)+(8*2)+(7*4)+(6*5)+(5*4)+(4*7)+(3*1)+(2*3)+(1*4)=144
144 % 10 = 4
So 1245471-34-4 is a valid CAS Registry Number.

Phosphomolybdic acid (PMA) - SiO2 as a heterogeneous solid acid catalyst for the one-pot synthesis of 2H-indazolo[1,2-b]phthalazine-triones

Sabitha, Gowravaram,Srinivas, Chitti,Raghavendar, Avula,Yadav, Jhillu Singh

, p. 1375 - 1380 (2010)

Phosphomolybdic acid (PMA) - SiO2 was found to be an efficient catalyst for the three-component condensation reaction of phthalhydrazide, 1,3-diketone, and aldehydes to produce 2H-indazolo[1,2-b]phthalazine-triones in excellent yields. The cata
