51759-79-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 51759-79-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,1,7,5 and 9 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 51759-79:
(7*5)+(6*1)+(5*7)+(4*5)+(3*9)+(2*7)+(1*9)=146
146 % 10 = 6
So 51759-79-6 is a valid CAS Registry Number.

SYNTHESIS OF THE NATURAL ENANTIOMERS OF ASCOCHLORIN, ASCOFURANONE AND ASCOFURANOL
Mori, Kenji,Takechi, Shozo
, p. 3049 - 3062 (2007/10/02)
Three fungal metabolites with a common structural feature as prenylated phenols were synthesized in their naturally occuring and optically active forms: ascochlorin benzaldehyde>, ascofuranone and ascofuranol benzaldehyde>. (+)-Ascofuranone and (+)-ascofuranol were also synthesized.By the present synthesis the absolute configuration of the natural (-)-ascofuranol was established as (1''S,4''S).
