Check Digit Verification of cas no

The CAS Registry Mumber 39491-37-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,9,4,9 and 1 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 39491-37:
(7*3)+(6*9)+(5*4)+(4*9)+(3*1)+(2*3)+(1*7)=147
147 % 10 = 7
So 39491-37-7 is a valid CAS Registry Number.

Steroidal saponins from Nolina recurvata stems and their inhibitory activity on cyclic AMP phosphodiesterase

Mimaki, Yoshihiro,Takaashi, Yoko,Kuroda, Minpei,Sashida, Yutaka,Nikaido, Tamotsu

, p. 1609 - 1615 (2007/10/03)

Seven steroidal saponins were isolated from the stems of Nolina recurvata, five of which appeared to be new compounds and were assigned as spirosta-5,25(27)-diene-1β,3β-diol (neuruscogenin) 1-O-{O-α-L- rhamnopyranosyl-(1 → 2)-O-[β-D-xylopyranosyl-(1 → 3)-α-L- arabinopyranoside}, (25S)-spirost-5-ene-1β,3β-diol [(25S)-ruscogenin] 1- O-{O-α-L-rhamnopyranosyl-(1 → 2)-O-[β-D-xylopyranosyl-(1 → 3)]-α-L- arabinopyranoside}, neuruscogenin 1-O-{O-α-L-rhamnopyranosyl-(1 → 2)-O- [β-D-xylopyranosyl-(1 → 3)]-β-D-fucopyranoside}, 26-O-β-D- glucopyranosyl-22-O-methylfurosta-5,25(27)-diene-1β,3β,22ζ,26-tetrol 1-O- {-O-α-L-rhamnopyranosyl-(1 → 2)-O-[β-D-xylopyranosyl-(1 → 3)]-α-L- arabinopyranoside} and 26-O-β-D-glucopyranosylfurosta-5,20(22),25(27)- triene-1β,3β,26-triol 1-O-{O-α-L-rhamnopyranosyl-(1 → 2)-α-L- arabinopyranoside}. The isolated saponins were evaluated for their inhibitory activity on cyclic AMP phosphodiesterase to identify new compounds with medicinal potential.
