Check Digit Verification of cas no

The CAS Registry Mumber 73013-89-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,0,1 and 3 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 73013-89:
(7*7)+(6*3)+(5*0)+(4*1)+(3*3)+(2*8)+(1*9)=105
105 % 10 = 5
So 73013-89-5 is a valid CAS Registry Number.

Nucleophile and Nucleofuge Effects, Catalysis, and Stereochemistry in Vinylic Substitution of Electrophilic Nitro Olefins

Rappoport, Zvi,Topol, Alain

, p. 5967 - 5977 (2007/10/02)

The substitution of (E)- and (Z)-β-iodo-α-nitrostilbenes (E-3-I and Z-3-I) and of the (E)-β-chloro (E-3-Cl) and of (E)-β-nitro (E-3-NO2) analogues with several nucleophiles were studied in MeCN and EtOH.Amine catalysis in the substitution with morpholine
