Check Digit Verification of cas no
The CAS Registry Mumber 18872-50-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,8,7 and 2 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 18872-50:
(7*1)+(6*8)+(5*8)+(4*7)+(3*2)+(2*5)+(1*0)=139
139 % 10 = 9
So 18872-50-9 is a valid CAS Registry Number.

PROCESS FOR PREPARATION OF PHOSPHORIC ESTERS
-
Page 7-8, (2010/11/30)
A process for preparing a phosphoric ester, comprising: Step (1) of reacting naphthol with phosphorus oxychloride in a molar ratio of 1:1.3 or more in the presence of a metallic halide and removing unreacted phosphorus oxychloride and Step (2) of reacting the reaction product of Step (1) with phenol in a molar ratio (molar ratio of chlorine contained in the reaction product to phenol) of 1:1-1.5 and removing hydrogen chloride produced as a by-product to thereby obtain a phosphoric ester represented by the general formula (I): wherein n is 1 or 2.
