Check Digit Verification of cas no

The CAS Registry Mumber 53911-87-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,3,9,1 and 1 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 53911-87:
(7*5)+(6*3)+(5*9)+(4*1)+(3*1)+(2*8)+(1*7)=128
128 % 10 = 8
So 53911-87-8 is a valid CAS Registry Number.

Formation of Allyl and Cyclopropylcarbinyl Sulphides in the Regiospecific Reactions of Arenesulphenyl Chlorides with Allyl- and But-3-enyl-cobaloximes

Ashcroft, Martyn R.,Gupta, B. Dass,Johnson, Michael D.

, p. 2021 - 2025 (2007/10/02)

Allyl- and substituted-allyl-bis(dimethylglyoximato)pyridinecobalt(III) complexes react regiospecifically with 2,4-dinitrobenzenesulphenyl chloride to give moderate (30-45percent) yields of the corresponding rearranged allyl 2,4-dinitrophenyl sulphides.The corresponding rearranged allyl derivative of the dimethylglyoxime is a major by-product.But-3-enylbis(dimethylglyoximato)pyridinecobalt(III) complexes also react regiospecifically to give cyclopropylmethyl 2,4-dinitrophenyl sulphides.The reactions are interpreted in terms of an electrophilic attack of the sulphur on the γ- and δ-carbon of the allyl- or butenyl-ligand, respectively, with concurrent or subsequent loss of cobaloxime(III), and with concurrent or subsequent cyclisation of the organic ligand in the case of the butenyl complexes.Benzenesulphenyl bromide and chloride react much more slowly and their reaction with allylbis(dimethylglyoximato)pyridinecobalt(III) has been briefly explored.
