87902-65-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 87902-65-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,9,0 and 2 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 87902-65:
(7*8)+(6*7)+(5*9)+(4*0)+(3*2)+(2*6)+(1*5)=166
166 % 10 = 6
So 87902-65-6 is a valid CAS Registry Number.

THE PHOTOCHEMISTRY OF 1,2,2-TRIMESITYLETHANONE
Hart, Harold,Lin, Lon-Tang W.
, p. 575 - 578 (2007/10/02)
Irradiation of 1,2,2-trimesitylethanone 1 gives the enol ethers 3 via 1,3-mesityl shift in a highly efficient process; the postulated intermediacy of 1 in the photoisomerisation of enol 2 is confirmed.
