Check Digit Verification of cas no

The CAS Registry Mumber 1265968-75-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,5,9,6 and 8 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1265968-75:
(9*1)+(8*2)+(7*6)+(6*5)+(5*9)+(4*6)+(3*8)+(2*7)+(1*5)=209
209 % 10 = 9
So 1265968-75-9 is a valid CAS Registry Number.

Selective synthesis of α-fluoro-β-keto-and α-fluoro- β-aminophosphonates via electrophilic fluorination by selectfluor

Radwan-Olszewska, Kinga,Palacios, Francisco,Kafarski, Pawel

, p. 1170 - 1173 (2011)

A series of α-mono-and α,α-difluoro-β- ketophosphonates were synthesized in moderate to good yields with excellent selectivities via electrophilic fluorination by Selectfluor. Subsequently, synthetic potential of the obtained α-monofluoro-β-ketophosphonates was demonstrated by their application in synthesis of α-monofluoro-β- aminophosphonates, useful building blocks in the preparation of phosphapeptides.
