Check Digit Verification of cas no

The CAS Registry Mumber 128801-17-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,8,0 and 1 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 128801-17:
(8*1)+(7*2)+(6*8)+(5*8)+(4*0)+(3*1)+(2*1)+(1*7)=122
122 % 10 = 2
So 128801-17-2 is a valid CAS Registry Number.

ALKYLATION OF ?-DONATING COMPOUNDS BY METHOXYALLENE-ARYLSULPHENYLCHLORIDE ADDUCTS

Smolyakova, I. P.,Smit, V. A.,Lutsenko, A. I.,Daeva, E. D.

, p. 101 - 107 (2007/10/02)

Reaction of methoxyallene with arylsulphenyl chlorides proceeds nonselectively with formation of mixtures of 1,2- and 2,3-arylthiochloro adducts, the composition of which depends on the nature of the reagent and solvent. ?-Donating compounds of various types in the presence of Lewis acids are alkylated by adducts of methoxyallene with arylsulphenyl chlorides and primarily products are formed by attack at the C3 atom of the reagent.
