Check Digit Verification of cas no

The CAS Registry Mumber 106656-55-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,6,6,5 and 6 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 106656-55:
(8*1)+(7*0)+(6*6)+(5*6)+(4*5)+(3*6)+(2*5)+(1*5)=127
127 % 10 = 7
So 106656-55-7 is a valid CAS Registry Number.

NMR Spectra and Stereochemistry of 2-(Piperidin-2-ylmethyl)cycloalkanols

Begley, Michael J.,Crabb, Trevor A.,Roch, Olive G.

, p. 292 - 296 (1986)

2-(Piperidin-2-ylmethyl)cycloalkanols have been synthesized by the reaction between 2-picolyllithium and cycloalkene oxides, followed by catalytic hydrogenation of the resulting 2-(pyridin-2-ylmethyl)cycloalkanols.The configurations of the 2-(piperidin-2-yl-methyl)cycloalkanols were assigned by comparing their 13C and 1H NMR parameters with those of 2-(piperidin-2-ylmethyl)cyclohexanols of known (x-ray) configuration.
