Check Digit Verification of cas no

The CAS Registry Mumber 120383-89-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,0,3,8 and 3 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 120383-89:
(8*1)+(7*2)+(6*0)+(5*3)+(4*8)+(3*3)+(2*8)+(1*9)=103
103 % 10 = 3
So 120383-89-3 is a valid CAS Registry Number.

BENZYL- and 2- AND 4-NITROBENZYLCYCLOPROPANES AND THEIR REACTION WITH ORGANIC ACIDS

Fedotov, A. N.,Trofimova, E. V.,Mochalov, S. S.,Shabarov, Yu. S.

, p. 1272 - 1275 (2007/10/02)

The nitration of benzylcyclopropane and its transformations in organic acids were studied.Under the conditions of electrophilic nitration the small ring is preserved, while the ratio of the o- and p-nitrophenyl derivatives amounts to 1.1:1.The reaction of benzylcyclopropane with formic and acetic acids takes place with the addition of the fragments of the acids at the 1,2-bond of the three-carbon ring; o- and p-nitrobenzylcyclopropanes do not react with formic and acetic acids, with trifluoroacetic acid they form trifluoroacetates, and in the case of the ortho-substituted isomer nucleophilic assistance from the nitro group is observed.
