Check Digit Verification of cas no

The CAS Registry Mumber 887629-72-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,8,7,6,2 and 9 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 887629-72:
(8*8)+(7*8)+(6*7)+(5*6)+(4*2)+(3*9)+(2*7)+(1*2)=243
243 % 10 = 3
So 887629-72-3 is a valid CAS Registry Number.

Solvent free selective dehydrogenation of indolic and carbazolic molecules with an iridium pincer catalyst

Brayton, Daniel F.,Jensen, Craig M.

, p. 5987 - 5989 (2014/05/20)

A previously known iridium POCOP pincer catalyst was found to selectively dehydrogenate the heterocyclic portion of several indolic and carbazolic molecules. These molecules were found to have an "activity window" (172-178 °C) upon which only the heterocyclic ring underwent dehydrogenation. All reactions were run solvent free, yields for selected substrates were excellent, and the products were isolated by either distillation or alumina plug filtration. the Partner Organisations 2014.
