83252-95-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 83252-95-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,2,5 and 2 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 83252-95:
(7*8)+(6*3)+(5*2)+(4*5)+(3*2)+(2*9)+(1*5)=133
133 % 10 = 3
So 83252-95-3 is a valid CAS Registry Number.

Phosphine oxydes Ph2P(O)CH(SO2C6H4X)2 are reversibly izomerised to ylides with a P-OH group Ph2P(OH)=C(SO2C6H4X)2.The phosphine oxyde-P-OH ylid equilibrium depends on the solvent nature, temperature and substituents X at the SO2C6H4X group.
