Check Digit Verification of cas no
The CAS Registry Mumber 87274-19-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,2,7 and 4 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 87274-19:
(7*8)+(6*7)+(5*2)+(4*7)+(3*4)+(2*1)+(1*9)=159
159 % 10 = 9
So 87274-19-9 is a valid CAS Registry Number.

PHOTOCHEMISTRY OF α,α-DISUBSTITUTED BICYCLIC CYCLOBUTANONES - A POTENTIAL THERMAL-PHOTOCHEMICAL METATHESIS REACTION
Lee-Ruff, Edward,Hopkinson, Alan C.,Kazarians-Moghaddam, Hira
, p. 2067 - 2070 (2007/10/02)
Under certain conditions the photolysis of α,α-disubstituted cyclobutanones give terminal olefinic esters.A two-stage thermal photochemical metathesis is described.
