653584-99-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 653584-99-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,5,3,5,8 and 4 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 653584-99:
(8*6)+(7*5)+(6*3)+(5*5)+(4*8)+(3*4)+(2*9)+(1*9)=197
197 % 10 = 7
So 653584-99-7 is a valid CAS Registry Number.

Cristau,Herve,Loiseau,Virieux
, p. 2216 - 2220 (2007/10/03)
The synthesis of a new series of arylhydroxymethylphosphinic acid derivatives is described. The protected compounds were prepared by a palladium(0) catalysed arylation of ethyl benzyloxymethylphosphinate with aryl halides. Subsequent hydrogenolysis of the
