64931-12-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 64931-12-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,4,9,3 and 1 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 64931-12:
(7*6)+(6*4)+(5*9)+(4*3)+(3*1)+(2*1)+(1*2)=130
130 % 10 = 0
So 64931-12-0 is a valid CAS Registry Number.

TAUTOMERIE OXYDE DE PHOSPHINO-YLURIQUE

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.
