113216-88-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 113216-88-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,3,2,1 and 6 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 113216-88:
(8*1)+(7*1)+(6*3)+(5*2)+(4*1)+(3*6)+(2*8)+(1*8)=89
89 % 10 = 9
So 113216-88-9 is a valid CAS Registry Number.

An improved synthesis of epibrassinolide is described.The product is the first of a group of brassinosteroids, which has found use a plant growth regulator.Among the proposed improvements for its production the most important position is the development of a stereoselective method for construction of the side chain by the oxidation of the Δ22-bond with osmium tetroxide in the presence of 10,11-dihydroquinidine p-chlorobenzoate.
