Check Digit Verification of cas no

The CAS Registry Mumber 167155-75-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,7,1,5 and 5 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 167155-75:
(8*1)+(7*6)+(6*7)+(5*1)+(4*5)+(3*5)+(2*7)+(1*5)=151
151 % 10 = 1
So 167155-75-1 is a valid CAS Registry Number.

Stereochemistry of C-6 nucleophilic displacements on 1,1- difluorocyclopropyldibenzosuberanyl substrates. An improved synthesis of multidrug resistance modulator LY335979 trihydrochloride

Barnett, Charles J.,Huff, Bret,Kobierski, Michael E.,Letourneau, Michael,Wilson, Thomas M.

, p. 7653 - 7660 (2004)

Studies of the displacement chemistry of 1,1- difluorocyclopropyldibenzosuberanyl alcohol 4 and its activated bromide derivative 6 have led to an improved approach to anti-2, a key precursor to LY335979 3HCl (1). Bromination of either syn-4 or anti-4 gave
