Check Digit Verification of cas no

The CAS Registry Mumber 80459-76-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,4,5 and 9 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 80459-76:
(7*8)+(6*0)+(5*4)+(4*5)+(3*9)+(2*7)+(1*6)=143
143 % 10 = 3
So 80459-76-3 is a valid CAS Registry Number.

Synthesis and Plant Growth-promoting Activity of Brassinolide Analogues

Wada, Kojiro,Marumo, Shingo

, p. 2579 - 2586 (2007/10/02)

The analogues of brassinolide, 15, 19-23 and 30, were synthezised via key intermediate 5 from stigmasterol.Compound 15 which has the same functional groups as brassinolide on rings A and B showed one tenth of the activity of brassinolide in the lamina inclination test on rice seedlings.However, other analogues with modified ring A were poorly active, and an analogue with modified ring B, 6-oxa-ketone 30, showed only one hundredth of the activity of its 7-oxa-ketone isomer, 29, suggesting that the 2α,3α-dihydroxy-7-oxa-6-ketone moiety is one of the requisites fro the biological activity.
