Check Digit Verification of cas no
The CAS Registry Mumber 115-87-7 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,1 and 5 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 115-87:
(5*1)+(4*1)+(3*5)+(2*8)+(1*7)=47
47 % 10 = 7
So 115-87-7 is a valid CAS Registry Number.

Abstract: The possibility of controlling the composition of a mixture of triphenyl phosphate, p-tert-butylphenyl diphenyl phosphate, di(p-tert-butylphenyl)phenyl phosphate, and tri(p-tert-butylphenyl) phosphate, formed by transesterification of triphenyl phosphate with p-tert-butylphenol, was demonstrated. The amount of p-tert-butylphenol necessary for transesterification of triphenyl phosphate to yield a mixture of phosphates of required composition was determined. If necessary, the composition of the phosphates can be adjusted by selective distillation of triphenyl phosphate in a vacuum.
