149183-66-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 149183-66-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,9,1,8 and 3 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 149183-66:
(8*1)+(7*4)+(6*9)+(5*1)+(4*8)+(3*3)+(2*6)+(1*6)=154
154 % 10 = 4
So 149183-66-4 is a valid CAS Registry Number.

Saikosaponins from Taverniera aegyptiaca
Hassanean
, p. 693 - 697 (1998)
By tracing the UV triplet of heteroannular dienes, three novel saikosaponins were isolated from the root bark of Taverniera aegyptiaca. They were identified as 22β-hydroxyolean-11,13(18)-dien-3β-yl-β-D- glucopyranoside, 1β,22β-dihydroxyolean-11,13(18)-dien-3β-yl-β-D- gLucopyranoside and 1β,22β-dihydroxyolean- 11,13(18)-dien-3β-yl-β-D- xylopyranosyl(1 → 2)β-D-glucopyranoside on the basis of chemical and spectral evidences.
