Check Digit Verification of cas no

The CAS Registry Mumber 310419-98-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,1,0,4,1 and 9 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 310419-98:
(8*3)+(7*1)+(6*0)+(5*4)+(4*1)+(3*9)+(2*9)+(1*8)=108
108 % 10 = 8
So 310419-98-8 is a valid CAS Registry Number.

Optical resolution of 5-alkyl-δ-valerolactones and synthesis of optically active 5-fluoroalkanols

Riswoko, Asep,Aoki, Yoshio,Hirose, Takuji,Nohira, Hiroyuki

, p. 33 - 39 (2002)

Optical resolutions of 5-alkyl-δ-valerolactones were carried out by derivatization to the diastereomeric amides, in which (R)-(+)-1-(1-naphthyl)ethylamine or (S)-(-)-1-phenylethylamine were used as resolving agents. Optically active 5-fluoroalkanols, useful intermediates for fluorinated ferroelectric liquid crystals, were derived from the resolved lactones in four steps without racemization.
