Check Digit Verification of cas no

The CAS Registry Mumber 138715-25-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,7,1 and 5 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 138715-25:
(8*1)+(7*3)+(6*8)+(5*7)+(4*1)+(3*5)+(2*2)+(1*5)=140
140 % 10 = 0
So 138715-25-0 is a valid CAS Registry Number.

Synthesis of (4S,5R)-(-)-4-Methyl-5-phenyloxazolidine-2-selone: A Chiral Auxiliary Reagent Capable of Detecting the Enantiomers of (R,S)-Lipoic Acid by 77Se Nuclear Magnetic Resonance Spectroscopy

Silks, Louis A.,Peng, Jie,Odom, Jerome D.,Dunlap, R. Bruce

, p. 2495 - 2498 (1991)

(4S,5R)-(-)-4-Methyl-5-phenyloxazolidine-2-selone was constructed in 5 steps on the 10-gram scale. 77Se NMR spectroscopic studies revealed that this selone served as a remarkably sensitive chiral auxiliary agent which readily distinguished the selone-coup
