Check Digit Verification of cas no

The CAS Registry Mumber 259729-27-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,9,7,2 and 9 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 259729-27:
(8*2)+(7*5)+(6*9)+(5*7)+(4*2)+(3*9)+(2*2)+(1*7)=186
186 % 10 = 6
So 259729-27-6 is a valid CAS Registry Number.

Enantioselective borohydride reduction of N-diphenylphosphinyl imines using optically active cobalt(II) complex catalysts

Sugi, Kiyoaki D.,Nagata, Takushi,Yamada, Tohru,Mukaiyama, Teruaki

, p. 493 - 494 (1997)

The enantioselective borohydride reduction using optically active cobalt(II) complex catalysts was successfully applied to various aryl N-diphenylphosphinyl imines, and the corresponding reduced products were obtained in good yields with high enantiomeric excesses (up to 99% ee). The optically active primary amines were obtained by the successive hydrolysis under mild conditions.
