Check Digit Verification of cas no
The CAS Registry Mumber 141843-89-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,1,8,4 and 3 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 141843-89:
(8*1)+(7*4)+(6*1)+(5*8)+(4*4)+(3*3)+(2*8)+(1*9)=132
132 % 10 = 2
So 141843-89-2 is a valid CAS Registry Number.

A selective removal of benzyl protecting groups in arylphosphate esters with bromotrimethylsilane
Lazar,Guillaumet
, p. 923 - 931 (2007/10/02)
Bromotrimethylsilane (BTMS) is shown to be an effectively selective reagent for the debenzylation of dibenzyl arylphosphate esters to give the corresponding arylphosphate acids and does not affect other functional groups also present in the molecular stru
