Check Digit Verification of cas no

The CAS Registry Mumber 123559-06-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,3,5,5 and 9 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 123559-06:
(8*1)+(7*2)+(6*3)+(5*5)+(4*5)+(3*9)+(2*0)+(1*6)=118
118 % 10 = 8
So 123559-06-8 is a valid CAS Registry Number.

Reactions of α-hydroxyketene dithioacetals with Lawesson's reagent: An efficient method for the synthesis of α,β-unsaturated dithioesters

Nair, Satheesh K.,Jose, Ann Maria,Asokan

, p. 1261 - 1264 (2005)

The α-hydroxyketene dithioacetals 2 and 5, obtained from α-oxoketene dithioacetals by the 1,2-reduction or the 1,2-addition of carbon nucleophiles, on treatment with Lawesson's reagent afforded α,β-unsaturated dithioesters 3 and 6 in good yields. Georg Th

STUDIES ON DIELS-ALDER CYCLOADDITIONS OF VINYLKETENE DITHIOACETALS

Gupta, Arun K.,Ila, Hiriyakkanavar,Junjappa, Hiriyakkanavar

, p. 1509 - 1516 (2007/10/02)

The Diels-Alder cycloadditions of the acyclic and cyclic vinylketene dithioacetals 4 prepared from the corresponding oxoketene dithioacetals 2, either by 1,2-addition of methylmagnesium iodide and subsequent dehydration or by Wittig reaction, were studied
