The CAS Registry Mumber 120542-10-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,0,5,4 and 2 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 120542-10:
(8*1)+(7*2)+(6*0)+(5*5)+(4*4)+(3*2)+(2*1)+(1*0)=71
71 % 10 = 1
So 120542-10-1 is a valid CAS Registry Number.

Convenient Preparation of Alkyl Benzyl Imidodicarbonates, Useful Reagents for the Direct Synthesis of Protected Amines

Grehn, Leif,Almeida, M. Lurdes S.,Ragnarsson, Ulf

, p. 992 - 994 (1988)

New mixed alkyl benzyl imidodicarbonates were prepared by reaction of benzyloxycarbonyl isocyanate with appropriate alcohols.This simple procedure also furnished alternative, more convenient routes to dibenzyl and benzyl 9-fluorenylmethyl imidodicarbonates.The substances are of interest as potential Gabriel reagents.Completely selective removal of one of the alkoxycarbonyl groups from the N-atom of the imidodicarbonates was demonstrated in several instances, giving benzyl carbamate or the alternative carbamate.
