Check Digit Verification of cas no

The CAS Registry Mumber 213914-70-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,3,9,1 and 4 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 213914-70:
(8*2)+(7*1)+(6*3)+(5*9)+(4*1)+(3*4)+(2*7)+(1*0)=116
116 % 10 = 6
So 213914-70-6 is a valid CAS Registry Number.

A practical synthesis of optically active (R)-2-propyloctanoic acid: Therapeutic agent for Alzheimer's disease

Hasegawa, Tomoyuki,Yamamoto, Hisashi

, p. 423 - 428 (2000)

(R)-2-Propyloctanoic acid has been developed as a novel therapeutic agent for Alzheimer's disease. A large-scale synthesis of this candidate was achieved by using Oppolzer's camphorsultam as a chiral auxiliary under improved conditions. It was essential for the successful synthesis of this compound to utilize a new removal method for the chiral source with a combination of tetrabutylammonium hydroxide and hydrogen peroxide. The present process afforded the desired product in high yield with high optical purity.
