Check Digit Verification of cas no

The CAS Registry Mumber 31239-57-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,1,2,3 and 9 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 31239-57:
(7*3)+(6*1)+(5*2)+(4*3)+(3*9)+(2*5)+(1*7)=93
93 % 10 = 3
So 31239-57-3 is a valid CAS Registry Number.

BRASSINOSTEROIDS WITH A CHOLESTANE SIDE CHAIN

Kohout, Ladislav,Strnad, Miroslav

, p. 447 - 458 (2007/10/02)

The synthesis of 2α,3α-dihydroxy-B-homo-7-oxa-cholestan-6-one (VI), 2β,3β-dihydroxy-B-homo-7-oxa-5α-cholestan-6-one (VIII) and 2α,3α-dihydroxy-B-homo-6-oxa-5α-cholestan-7-one (XI) is described.The activity of these brassinosteroids in the bean second internode bioassay is lower than the activity of 24-epibrassinolide (XXI).
