137043-93-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 137043-93-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,0,4 and 3 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 137043-93:
(8*1)+(7*3)+(6*7)+(5*0)+(4*4)+(3*3)+(2*9)+(1*3)=117
117 % 10 = 7
So 137043-93-7 is a valid CAS Registry Number.

Bulladecin and atemotetrolin, two bis-tetrahydrofuran acetogenins from Annona atemoya seeds
Duret, Philippe,Hocquemiller, Reynald,Cave, Andre
, p. 499 - 506 (1998)
Two new C37 tetrahydroxy adjacent bis-tetrahydrofuran acetogenins with a vicinal diol, bulladecin and atemotetrolin, were isolated from the methanol extract of Annona atemoya seeds and characterized by spectroscopic techniques. In addition the known compounds, cherimolin-2 and almunequin, were isolated and identified.
