Check Digit Verification of cas no

The CAS Registry Mumber 138715-29-4 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 9 respectively.
Calculate Digit Verification of CAS Registry Number 138715-29:
(8*1)+(7*3)+(6*8)+(5*7)+(4*1)+(3*5)+(2*2)+(1*9)=144
144 % 10 = 4
So 138715-29-4 is a valid CAS Registry Number.

Synthesis and Characterization of Acylated Chiral Oxazolidine-2-selones: Selone Chiral Derivatizing Agents for the Detection and Quantitation of Remotely Disposed Chiral Centers

Peng, Jie,Barr, Mary E.,Ashburn, David A.,Lebioda, Lukasz,Garber, Albert R.,et al.

, p. 5540 - 5549 (2007/10/03)

Racemic and chiral carboxylic acids and acid chlorides are coupled cleanly to oxazolidine-2-selone chiral derivatizing agents (CDA's) with yields ranging from 85 to 99percent. 77Se NMR spectroscopy provides a highly sensitive method for the determination
