429620-50-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 429620-50-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,2,9,6,2 and 0 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 429620-50:
(8*4)+(7*2)+(6*9)+(5*6)+(4*2)+(3*0)+(2*5)+(1*0)=148
148 % 10 = 8
So 429620-50-8 is a valid CAS Registry Number.

Synthesis and antimicrobial activity of novel benzo[f]coumarin compounds
Zaki,Elossaily,Kamal El-Dean
, p. 639 - 646 (2013/02/23)
The acetyl benzo[f]coumarin condensed with phenyl hydrazine to afford the corresponding phenyl hydrazone which cyclized into the pyrazolyl benzocoumarin under Vilsmeier reaction conditions. The pyrazolylaldehyde was used as starting material for synthesis
