64504-52-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 64504-52-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,4,5,0 and 4 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 64504-52:
(7*6)+(6*4)+(5*5)+(4*0)+(3*4)+(2*5)+(1*2)=115
115 % 10 = 5
So 64504-52-5 is a valid CAS Registry Number.

ANTHELIOLIDE A AND B: TWO NEW C24-ACETOACETYLATED DITERPENOIDS OF THE SOFT CORAL ANTHELIA GLAUCA
Green, D.,Carmely, S.,Benayahu, Y.,Kashman, Y.
, p. 1605 - 1608 (2007/10/02)
Two new derivatives of xenicin and two novel C24 - acetoacetylated diterpenoids, antheliolide A and B (8 and 9) have been isolated from Anthelia glauca.The structure of compounds 8 and 9 was established by 2D-NMR techniques and a biogenesis starting from GeGePP via xeniaphyllane is suggested.
