274255-51-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 274255-51-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,7,4,2,5 and 5 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 274255-51:
(8*2)+(7*7)+(6*4)+(5*2)+(4*5)+(3*5)+(2*5)+(1*1)=145
145 % 10 = 5
So 274255-51-5 is a valid CAS Registry Number.

Synthesis of medium-sized carbocyclic ketones via the intramolecular B-alkyl Liebeskind-Srogl coupling reaction
Tsuna, Kazuhiro,Noguchi, Naoyoshi,Nakada, Masahisa
, p. 7202 - 7205 (2011)
Synthesis of medium-sized carbocyclic ketones via the intramolecular B-alkyl Liebeskind-Srogl coupling reaction is described. The sequence of hydroboration of ω-alkenyl thiol ester with 9-BBN and the Liebeskind-Srogl reaction results in the formation of m
