Check Digit Verification of cas no

The CAS Registry Mumber 121262-09-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,2,6 and 2 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 121262-09:
(8*1)+(7*2)+(6*1)+(5*2)+(4*6)+(3*2)+(2*0)+(1*9)=77
77 % 10 = 7
So 121262-09-7 is a valid CAS Registry Number.

CRITERIA FOR ESTABLISHMENT OF THREE-DIMENSIONAL STRUCTURES OF DIELS-ALDER ADDUCTS IN THE ISOINDOLE SERIES. 2. REACTION OF 1,2-DISUBSTITUTED ISOINDOLES WITH MALEINIMIDE DERIVATIVES

Kovtunenko, V. A.,Voitenko, Z. V.,Kucherenko, T. T.,Turov, A. V.,Tyltin, A. K.,Babichev, F. S.

, p. 161 - 172 (2007/10/02)

The Diels-Alder reaction of a series of 1,2-disubstituted isoindoles with maleinimide derivatives under conditions of kinetic and thermodynamic control was investigated.Criteria for the establishment of the three-dimensional structures of the adducts obtained were found.The possibility of supra-antara cycloaddition and the formation of 1:2 adducts was demonstrated.
