Check Digit Verification of cas no

The CAS Registry Mumber 22819-90-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,2,8,1 and 9 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 22819-90:
(7*2)+(6*2)+(5*8)+(4*1)+(3*9)+(2*9)+(1*0)=115
115 % 10 = 5
So 22819-90-5 is a valid CAS Registry Number.

MECHANISMS OF FREE-RADICAL REACTIONS. XIV. SELECTIVITY OF FREE-RADICAL CHLORINATION OF VALERIC ACID DERIVATIVES WITH ARYLCHLOROIODONIUM CHLORIDES

Dneprovskii, A. S.,Krainyuchenko, I. V.

, p. 324 - 328 (2007/10/02)

The free-radical chlorination of C4H9Y compounds with arylchloroiodonium chlorides was investigated.The reaction of the secondary C-H bonds increases as they become further from the electronegative substituent.The reaction parameters were calculated from the ratio of the β- and γ-monochlorides by means of the Taft equation.The absolute value of ρ increases with the introduction of electronwithdrawing substituents into the arylchloroiodonium chloride molecule.
