183308-64-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 183308-64-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,3,3,0 and 8 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 183308-64:
(8*1)+(7*8)+(6*3)+(5*3)+(4*0)+(3*8)+(2*6)+(1*4)=137
137 % 10 = 7
So 183308-64-7 is a valid CAS Registry Number.

The first total synthesis of 15-epi-annonin I

Woehrle, Ingo,Classen, Arno,Peterek, Marcus,Scharf, Hans-Dieter

, p. 7001 - 7004 (1996)

The first total synthesis of the 15-epimer 1b of the naturally occurring acetogenin annonin I 1a is described. All stereogenic centres in the bis-THF subunit are controlled via successive Sharpless asymmetric epoxidations (AE). Alkyl side chains were attached directly to the core using alkyne-epoxide couplings.
