202-98-2 Usage

Uses

4,5-Methanochrysene shows moderate degree of carcinogenic activity. As a polycyclic aromatic hydrocarbon (PAH), it is considered as a pollutant.

Carcinogenicity

4H-Cyclopenta[def]chrysene was carcinogenic in two initiation–promotion experiments in mice.

Check Digit Verification of cas no

The CAS Registry Mumber 202-98-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 2,0 and 2 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 202-98:
(5*2)+(4*0)+(3*2)+(2*9)+(1*8)=42
42 % 10 = 2
So 202-98-2 is a valid CAS Registry Number.
