76711-27-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 76711-27-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,6,7,1 and 1 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 76711-27:
(7*7)+(6*6)+(5*7)+(4*1)+(3*1)+(2*2)+(1*7)=138
138 % 10 = 8
So 76711-27-8 is a valid CAS Registry Number.

The phosphines t-Bu2P-CH2R (R=H,Alk) react with CCl4 and CBr4 to give ylids with a halogen atom at P.Ylids t-Bu2P(Hlg)=CHR treated with CO2 and PhN=C=O give ketens t-Bu2P(O)-CR=C=O and ketenimines t-Bu2P(O)CR=C=NPh, respectively.
