475628-80-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 475628-80-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,7,5,6,2 and 8 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 475628-80:
(8*4)+(7*7)+(6*5)+(5*6)+(4*2)+(3*8)+(2*8)+(1*0)=189
189 % 10 = 9
So 475628-80-9 is a valid CAS Registry Number.

, p. 2640 - 2648 (2007/10/03)
The first synthesis of dibenzyl α,α-difluoro-β-ketophosphonates has been accomplished by an original fluorination reaction, namely addition of the F+ ion to the enolate form of the corresponding dibenzyl β-ketophosphonate. After an easy cleavag
