Check Digit Verification of cas no

The CAS Registry Mumber 90686-45-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,6,8 and 6 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 90686-45:
(7*9)+(6*0)+(5*6)+(4*8)+(3*6)+(2*4)+(1*5)=156
156 % 10 = 6
So 90686-45-6 is a valid CAS Registry Number.

Determination of the Absolute Configuration of Chiral Secondary Alcohols from Tetra-O-acetylglucosidation-Induced 1H Nuclear Magnetic Resonance Shifts

, p. 4918 - 4920 (2007/10/02)

Tetra-O-acetylglucosidation-induced 1H nuclear magnetic resonance shifts were found highly characteristic of the absolute configuration of representative examples of R and S chiral secondary alcohols.The most important chemical shift changes of structurally diagnostic value for the determination of the absolute configuration of alcohols concern the protons of the aglycone attached to the carbons at β-position relative to the oxygen atom.
