Check Digit Verification of cas no

The CAS Registry Mumber 62143-81-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,2,1,4 and 3 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 62143-81:
(7*6)+(6*2)+(5*1)+(4*4)+(3*3)+(2*8)+(1*1)=101
101 % 10 = 1
So 62143-81-1 is a valid CAS Registry Number.

N-(2-hydroxyaryl)benzamide synthesis from 2-nitroaryl benzoates via an Indium-mediated reduction-migration reaction

Lee, Hyejeong,Kim, Minki,Jun, Young Moo,Kim, Byeong Hyo,Lee, Byung Min

experimental part, p. 158 - 167 (2011/10/08)

A one-pot reduction-triggered N-(2-hydroxyaryl)benzamide synthesis from 2-nitroaryl benzoate substrates was investigated. In the presence of indium/AcOH in THF/H2O, 2-nitroaryl benzoates produced reasonable yields of the benzo group migrated N-
