68965-51-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 68965-51-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,8,9,6 and 5 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 68965-51:
(7*6)+(6*8)+(5*9)+(4*6)+(3*5)+(2*5)+(1*1)=185
185 % 10 = 5
So 68965-51-5 is a valid CAS Registry Number.

Iterative synthesis of alkenes by insertion of lithiated epoxides into boronic esters
Bojaryn, Kevin,Fritsch, Stefan,Hirschhaüser, Christoph
, p. 2218 - 2222 (2019)
The insertion of lithiated epoxides into boronic esters followed by thermal syn-elimination provides a stereospecific entry to alkenes. This process avoids transition metals and is amenable to iteration to provide higher substitution patterns.
