Check Digit Verification of cas no

The CAS Registry Mumber 78530-01-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,5,3 and 0 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 78530-01:
(7*7)+(6*8)+(5*5)+(4*3)+(3*0)+(2*0)+(1*1)=135
135 % 10 = 5
So 78530-01-5 is a valid CAS Registry Number.

STUDIES ON AROYL- AND ARYL-HYDRAZIDE DERIVATIVES FROM D-glycero-D-gulo-HEPTANO-1,4-LACTONE

Sharaf, Saber M.,Sallam, Mohammed A. E.,Shenawy, Hamdy A. El

, p. 39 - 48 (2007/10/02)

A series of aroyl- and aryl-hydrazide derivatives was prepared from D-glycero-D-gulo-heptono-1,4-lactone (1). the reactivity of the NH proton in these hydrazides, in terms of their dissociation constants (pKa), was determined from their electronic spectra, and correlated to the Hammett ? values of the substituents.Comparable reactivities of the NH protons for the compounds, and the effect of the substituent, were studied by n.m.r. spectroscopy.Decomposition of the aroylhydrazides with copper(II) sulfate or nitrous acid resulted in the regeneration of 1.
