263889-23-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 263889-23-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,6,3,8,8 and 9 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 263889-23:
(8*2)+(7*6)+(6*3)+(5*8)+(4*8)+(3*9)+(2*2)+(1*3)=182
182 % 10 = 2
So 263889-23-2 is a valid CAS Registry Number.

Diastereospecific fluorination of substituted azepanes
Patel, Alpesh Ramanlal,Liu, Fei
, p. 744 - 752 (2013/07/25)
Fluorination of bioactive compounds is an important step in drug discovery and development. Fluorination has been extensively studied in acyclic systems, carbocycles, and fused heterocycles. However, there is no report on fluorination of azepanes. As azep
