Check Digit Verification of cas no
The CAS Registry Mumber 83567-78-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,5,6 and 7 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 83567-78:
(7*8)+(6*3)+(5*5)+(4*6)+(3*7)+(2*7)+(1*8)=166
166 % 10 = 6
So 83567-78-6 is a valid CAS Registry Number.

Siladifluoromethylation and Deoxo-trifluoromethylation of PV-H Compounds with TMSCF3: Route to PV-CF2- Transfer Reagents and P-CF3 Compounds
Krishnamurti, Vinayak,Barrett, Colby,Prakash, G. K. Surya
, p. 1526 - 1529 (2019)
A method for siladifluoromethylation of dialkyl phosphonates and secondary phosphine oxides with TMSCF3 to produce nucleophilic PV-CF2- transfer reagents is disclosed, with multigram scale reactions included. Condition-dependent divergent reactivity under the established conditions is demonstrated by the formation of trifluoromethylphosphines. Both one-pot transformations are operationally simple and employ inexpensive materials. Mechanistic investigations suggest the divergent reactivity originates from a common intermediate, with Li+ concentration directing the chemoselectivity.
