Check Digit Verification of cas no

The CAS Registry Mumber 199797-86-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,9,7,9 and 7 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 199797-86:
(8*1)+(7*9)+(6*9)+(5*7)+(4*9)+(3*7)+(2*8)+(1*6)=239
239 % 10 = 9
So 199797-86-9 is a valid CAS Registry Number.

Efficient stereoselective synthesis of cis, syn-hydroxyitraconazole isomers

Tanoury, Gerald J.,Senanayake, Chris H.,Hett, Robert,Hong, Yaping,Wald, Stephen A.

, p. 7839 - 7842 (1997)

The first stereoselective synthesis of cis, syn-hydroxyitraconazole isomers via a tricomponent coupling strategy is described. The isomers are prepared from two chiral subunits and connected via an achiral linker. A highly stereoselective route to the cis,syn-isomers is presented.
