Check Digit Verification of cas no

The CAS Registry Mumber 80245-45-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,2,4 and 5 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 80245-45:
(7*8)+(6*0)+(5*2)+(4*4)+(3*5)+(2*4)+(1*5)=110
110 % 10 = 0
So 80245-45-0 is a valid CAS Registry Number.

Synthesis of Haemofluorone B Trimethyl Ether

Feutrill, Geoffrey I.,Whitelaw, Murray L.

, p. 1523 - 1528 (2007/10/02)

The revision of the structure of haemofluorone B to 5,8,9-trihydroxy-3H-naphthoxanthen-3-one is confirmed by the synthesis of its trimethyl ether by photochemical oxidative cyclization of 9-(3,4-dimethoxyphenyl)-4-hydroxy-2-methoxy-1H-phenalen-1-one.The conventional process for conjugate arylation of phenalenones has been improved by the use of aryllithium reagents.
