Check Digit Verification of cas no

The CAS Registry Mumber 191786-68-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,1,7,8 and 6 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 191786-68:
(8*1)+(7*9)+(6*1)+(5*7)+(4*8)+(3*6)+(2*6)+(1*8)=182
182 % 10 = 2
So 191786-68-2 is a valid CAS Registry Number.

Diastereoselective synthesis of 2'-deoxy and 2'-O-methyl dinucleoside (3',5')-methylphosphonates via alkoxymagnesium chloride-mediated nucleoside coupling

Daily,Schwartz,Riley,Arnold L.J.,Marvin,Scurria,Hopkins,Atkins,Garcia,Pirrung

, p. 417 - 432 (2007/10/03)

A diastereoselective dinucleoside methylphosphonate synthetic method that features coupling of diastereomerically pure 1,1,1,3,3,3-hexafluoro-2- propyl nucleoside-3'-O-methylphosphonate monomers with 3'-O-protected nucleoside monomers mediated by alkoxymagnesium chloride reagents is described. This synthetic method was found to be diastereospecific in the synthesis of selected 2'-deoxy dinucleoside methyphosphonates and diastereoselective in the synthesis of all sixteen 2'-O-methyl dinucleoside methylphosphonates.
