Check Digit Verification of cas no

The CAS Registry Mumber 102878-76-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,2,8,7 and 8 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 102878-76:
(8*1)+(7*0)+(6*2)+(5*8)+(4*7)+(3*8)+(2*7)+(1*6)=132
132 % 10 = 2
So 102878-76-2 is a valid CAS Registry Number.

THE CYCLISATION AND REARRANGEMENT OF THE NITRO DERIVATIVES OF AROMATIC HYDROCARBONS IN TRIFLUOROMETHANESULPHONIC ACID

Bullen, John V.,Ridd, John H.,Sabek, Omaima

, p. 291 - 296 (2007/10/02)

A number of the nitro derivatives of aromatic hydrocarbons undergo reactions in trifluoromethanesulphonic acid at ca. 100 deg C in which either the nitro group undergoes a 1,3-rearrangement or cyclisation occurs to form an anthranil.The rates and product composition have been determined for reactions in which the subsituents ortho to the nitro group are methyl or ethyl.For the rearrangement reaction to occur, it appears necessary that the nitro group should be initially between two alkyl substituents.The cyclisation reaction is significant only when one of the ortho-substituents is an ethyl group.
