Check Digit Verification of cas no

The CAS Registry Mumber 19953-61-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,9,5 and 3 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 19953-61:
(7*1)+(6*9)+(5*9)+(4*5)+(3*3)+(2*6)+(1*1)=148
148 % 10 = 8
So 19953-61-8 is a valid CAS Registry Number.

Hexamethonium bis(tribromide) (HMBTB) a recyclable and high bromine containing reagent

Paul, Bappi,Bhuyan, Bishal,Purkayastha, Debraj D.,Dhar, Siddhartha S.,Patel, Bhisma K.

, p. 5646 - 5650 (2015/09/21)

A recyclable and high bromine containing di-(tribromide) reagent, hexamethonium bis(tribromide) (HMBTB) has been synthesized and utilized for the bromination of various organic substrates. The spent reagent hexamethonium bromide (HMB) can be effectively recycled by regenerating and reusing it without significant loss of activity. The crystalline and stable bis(tribromide) is an effective storehouse of very high percentage of active bromine requiring just half an equivalent of it for complete bromination. Both the Br3- moieties in HMBTB are nearly linear with Br-Br-Br angle of 179.55°.
