Check Digit Verification of cas no

The CAS Registry Mumber 73434-46-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,4,3 and 4 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 73434-46:
(7*7)+(6*3)+(5*4)+(4*3)+(3*4)+(2*4)+(1*6)=125
125 % 10 = 5
So 73434-46-5 is a valid CAS Registry Number.

Stereochemical Course of the Haworth-Type Synthesis of Optically Active 2-(1-Methylpropyl)naphthalene

Menicagli, Rita,Piccolo, Oreste

, p. 2581 - 2585 (2007/10/02)

The preparation of (S)-2-(1-methylpropyl)naphthalene has been accomplished by starting from (S)-(1-methylpropyl)benzene with detectable racemization.The partially unstereospecific steps have been distinguished by evaluating the optical purity of key intermediates through chemical correlations with known optically active compounds.
