615580-90-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 615580-90-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,1,5,5,8 and 0 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 615580-90:
(8*6)+(7*1)+(6*5)+(5*5)+(4*8)+(3*0)+(2*9)+(1*0)=160
160 % 10 = 0
So 615580-90-0 is a valid CAS Registry Number.

, p. 8830 - 8835 (2007/10/03)
Synthesis of both enantiomers of annuionone A (1), an allelopathic agent isolated from Helianthus annuus (sunflower), was accomplished. The absolute configuration of the naturally occurring 1 was determined to be 1S,5R,8R.
