Check Digit Verification of cas no

The CAS Registry Mumber 18858-80-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,8,5 and 8 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 18858-80:
(7*1)+(6*8)+(5*8)+(4*5)+(3*8)+(2*8)+(1*0)=155
155 % 10 = 5
So 18858-80-5 is a valid CAS Registry Number.

Toward selective functionalisation of oligosilanes: Borane-catalysed dehydrogenative coupling of silanes with thiols

Harrison, Daniel J.,Edwards, David R.,McDonald, Robert,Rosenberg, Lisa

, p. 3401 - 3411 (2008/12/20)

Among established methods for transforming Si-H bonds, carbonyl hydrosilylation and heterodehydrogenative coupling with alcohols catalysed by B(C6F5)3 are shown to provide exceptionally clean routes to the derivatisation of tetra-substituted disilanes such as [Ph2SiH]2, giving no products resulting from Si-Si bond cleavage. Even higher activity is observed for the borane-catalysed dehydrogenative coupling of silanes with alkyl- and arylthiols, the first examples of such Si-S bond formation in the absence of a transition metal catalyst. Clean, quantitative syntheses of a range of thiosilanes are reported, and the lability of the Si-S linkage toward subsequent alcoholysis is investigated. The crystal structure of 2,3-disila-2,2,3,3-tetramethyl-1,4- benzodioxane is presented.
