Check Digit Verification of cas no

The CAS Registry Mumber 95903-44-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,5,9,0 and 3 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 95903-44:
(7*9)+(6*5)+(5*9)+(4*0)+(3*3)+(2*4)+(1*4)=159
159 % 10 = 9
So 95903-44-9 is a valid CAS Registry Number.

Regiochemistry of Nucleophilic Opening of β-Substituted Styrene Oxides with Thiolate Anions: Model Experiments in the Synthesis of Leukotriene Analogues

Marples, Brian A.,Saint, Christopher G.,Traynor, John R.

, p. 567 - 574 (2007/10/02)

β-Substituted trans-styrene oxides are cleaved with thiolate anions highly regioselectively by attack at the α-carbon whereas the cis-isomers are cleaved by attack at the α- and β-carbons.Cysteine, in a suitably protected form, similarly cleaves β-substituted trans-styrene oxides, thus allowing the synthesis of a simple LTE model.
