Check Digit Verification of cas no

The CAS Registry Mumber 146726-40-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,6,7,2 and 6 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 146726-40:
(8*1)+(7*4)+(6*6)+(5*7)+(4*2)+(3*6)+(2*4)+(1*0)=141
141 % 10 = 1
So 146726-40-1 is a valid CAS Registry Number.

, p. 3889 - 3904 (2007/10/02)

The title synthesis was achieved by employing highly cis-selective cyclopropanation of N-benzyl-N-vinylcarbamates with zinc-monofluorocarbenoid, deprotection of the formed N-benzyl-N-(cis-2-fluorocyclopropyl)carbamates, and optical resolution of the resul
