52611-78-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 52611-78-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,2,6,1 and 1 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 52611-78:
(7*5)+(6*2)+(5*6)+(4*1)+(3*1)+(2*7)+(1*8)=106
106 % 10 = 6
So 52611-78-6 is a valid CAS Registry Number.

Transformation of Grayanotoxin III to the 1,5-seco-Grayanotoxin Derivative, Grayanol B
Terai, Tadamasa,Kiyono, Koushi,Goto, Kunio
, p. 2711 - 2716 (2007/10/02)
Treatment of grayanotoxin (G) III with pyruvic acid in methanol gave the Δ1(10)-1,5-seco-G derivative.Photo-sensitized oxygenation of Δ1(10)-1,5-seco-G under UV light irradiation in methanol gave the 1(S)-perhydroxy- and 1(S)-hydroxy-1,5-seco-G derivatives.The IR and NMR data for Δ1(10)-1(S)-hydroxy-1,5-seco-G were identical with those of natural grayanol B described in the literature.
