Check Digit Verification of cas no

The CAS Registry Mumber 31503-10-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,1,5,0 and 3 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 31503-10:
(7*3)+(6*1)+(5*5)+(4*0)+(3*3)+(2*1)+(1*0)=63
63 % 10 = 3
So 31503-10-3 is a valid CAS Registry Number.

THE OCTANT RULE XXIII. ANTIOCTANT EFFECTS IN γ,δ-UNSATURATED KETONES

Toan, Vien Van,Lightner, David A.

, p. 5769 - 5774 (2007/10/02)

The exo and endo α-benzyl derivatives (1 and 2. respectively) of (+)-camphor have been synthesized and are found to exert a strong influence on the circular dichroism n?* Cotton effects: 1: Δε301max -0.36 (n-heptane) and 2: Δε302max +3.22, relative to camphor: Δε304max + 1.8 (n-heptane).Evidence for electric dipole transition moment coupling in these γ,δ-unsaturated systems is found in the n?* UV: 1: ε291max 84 (n-heptane) and 2: ε285max 303, relative to camphor: ε290max 25.
