Check Digit Verification of cas no

The CAS Registry Mumber 1800-30-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,8,0 and 0 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1800-30:
(6*1)+(5*8)+(4*0)+(3*0)+(2*3)+(1*0)=52
52 % 10 = 2
So 1800-30-2 is a valid CAS Registry Number.

ATTEMPTED PREPARATIONS OF PHOSPHORANES CONTAINING PERFLUOROPHENYL GROUPS

Denney, Donald B.,Denney, Dorothy Z.,Liu, Lun-Tsu

, p. 1 - 8 (2007/10/02)

The reaction of perfluorophenol with phosphorus pentachloride in the presence of triethylamine or χ-collidine yielded perfluoropentaphenoxyphosphorane, 5, along with perfluorotriphenylphosphate, 6, and perfluorodiphenyl ether, 7.Attempts to prepare penta(perfluorobenzyloxy)phosphorane, 12, by a number of methods failed.Similarly attempts to prepare perfluorothiophenylphosphorane, 19, always resulted in perfluorothiophenyl phosphite, 20, and perfluorodiphenyl disulfide, 21.
