78339-53-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 78339-53-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,3,3 and 9 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 78339-53:
(7*7)+(6*8)+(5*3)+(4*3)+(3*9)+(2*5)+(1*3)=164
164 % 10 = 4
So 78339-53-4 is a valid CAS Registry Number.

Takano, Seiichi,Goto, Emiko,Ogasawara, Kunio
, p. 5567 - 5570 (2007/10/02)
Using (S)-benzyl 2,3-epoxypropyl ether (1), the first stereoselective synthesis of (+)-nuciferol (14) and (+)-nuciferal (16) has been achieved.Employing the same methodology an enantioselective synthesis of (+)-α-curcumene (17) is also described.
