Check Digit Verification of cas no

The CAS Registry Mumber 1280126-09-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,8,0,1,2 and 6 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1280126-09:
(9*1)+(8*2)+(7*8)+(6*0)+(5*1)+(4*2)+(3*6)+(2*0)+(1*9)=121
121 % 10 = 1
So 1280126-09-1 is a valid CAS Registry Number.

Inherent oxygen preference in enolate monofluoromethylation and a synthetic entry to monofluoromethyl ethers

Nomura, Yoshinori,Tokunaga, Etsuko,Shibata, Norio

, p. 1885 - 1889 (2011/04/22)

Expect the unexpected: The self-stable salts 1, X=OTf, PF6, x=2, y=1, developed for electrophilic monofluoromethylation showed inherent selectivity for the O-alkylation of enolates, thus providing access to monofluoromethyl ethers, which are difficult to obtain by the direct electrophilic fluoromethylation of alcohols. Salt 1, X=BF4, x=0, y=3, in contrast leads to C-alkylated products.
