88126-91-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 88126-91-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,8,1,2 and 6 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 88126-91:
(7*8)+(6*8)+(5*1)+(4*2)+(3*6)+(2*9)+(1*1)=154
154 % 10 = 4
So 88126-91-4 is a valid CAS Registry Number.

The reaction of cyclohexylideneethenylphosphonic acid and its esters with arylselenenyl chlorides leads to the formation of 4-arylseleno-2-oxo-1-oxa-2-phospha-spiro(4,5)-3-decene derivatives.The dichloride of this acid with the same reagent cyclized only
