Check Digit Verification of cas no

The CAS Registry Mumber 42022-83-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,2,0,2 and 2 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 42022-83:
(7*4)+(6*2)+(5*0)+(4*2)+(3*2)+(2*8)+(1*3)=73
73 % 10 = 3
So 42022-83-3 is a valid CAS Registry Number.

PROCESS FOR MANUFACTURE OF PENTAERYTHRITOL DIPHOSPHITES

-

Page/Page column 4-5, (2008/06/13)

A method is disclosed for the production of pentaerythritol diphosphites of high spiro isomer content. The pentaerythritol diphosphites are produced via sequential transesterification of pentaerythritol with a monophosphite followed by a substituted phenol or other alcohol, wherein the transesterification reactions are carried out under controlled conditions of temperature and pressure. The unique reaction conditions result in intermediate and final pentaerythritol diphosphites of high spiro isomer content and high total yield of the diphosphites.
