Check Digit Verification of cas no
The CAS Registry Mumber 1049103-25-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,4,9,1,0 and 3 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1049103-25:
(9*1)+(8*0)+(7*4)+(6*9)+(5*1)+(4*0)+(3*3)+(2*2)+(1*5)=114
114 % 10 = 4
So 1049103-25-4 is a valid CAS Registry Number.

Selective mono-fluorination of diols via a cyclic acetal of N,N-diethyl-4-methoxybenzamide
Suwada, Mitsuhiro,Fukuhara, Tsuyoshi,Hara, Shoji
, p. 1121 - 1125 (2007)
Selective mono-fluorination of 1,2- and 1,3-diols was achieved using N,N-diethyl-4-methoxybenzamide diethyl acetal and Et3N-3HF. The reaction proceeds through a cyclic acetal of the benzamide, and only one hydroxy group was fluorinated and anot
