81795-15-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 81795-15-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,7,9 and 5 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 81795-15:
(7*8)+(6*1)+(5*7)+(4*9)+(3*5)+(2*1)+(1*5)=155
155 % 10 = 5
So 81795-15-5 is a valid CAS Registry Number.

STEREOSPECIFIC ANNELATIONS OF ETHYLENIC β-PHENYLSELENOETHERS BY ACID CATALYSIS
Rouessac, Annick,Rouessac, Francis
, p. 4165 - 4170 (2007/10/02)
It will be shown with several examples that it is possible to effect with exceptional ease on monounsaturated ethers, 1.5-phenylseleno group migration, quantitatively, by the action of anhydrous Lewis or Broensted acids at 0 deg C.However, the presence of
