29306-29-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 29306-29-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,9,3,0 and 6 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 29306-29:
(7*2)+(6*9)+(5*3)+(4*0)+(3*6)+(2*2)+(1*9)=114
114 % 10 = 4
So 29306-29-4 is a valid CAS Registry Number.

, p. 2759 - 2764 (1999)
Two new erythrinan alkaloids, 10,11-dioxoerythraline (1) and 8- oxoerythraline epoxide (5) have been isolated from flowers of Erythrina x bidwillii. Their structures were elucidated by spectroscopic analyses and chemical evidence. 8-Oxoerythraline epoxide is the first erythrinan alkaloid possessing an epoxy ring.
