Check Digit Verification of cas no

The CAS Registry Mumber 38434-99-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,8,4,3 and 4 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 38434-99:
(7*3)+(6*8)+(5*4)+(4*3)+(3*4)+(2*9)+(1*9)=140
140 % 10 = 0
So 38434-99-0 is a valid CAS Registry Number.

Concise formal synthesis of the bryostatin southern hemisphere (C17-C27)

Voight, Eric A.,Roethle, Paul A.,Burke, Steven D.

, p. 4534 - 4537 (2007/10/03)

An efficient synthesis of Hale and co-workers' C17-C27 bryostatin southern hemisphere intermediate has been accomplished in six steps and 33% overall yield from (R)-2-(benzyloxy)propanal. The synthesis features a one-pot DIBALH/HWE ester homologation as w

A short synthetic pathway to a fully-functionalized southern hemisphere of the antitumor macrolide bryostatin 1.

Hale,Frigerio,Manaviazar

, p. 3791 - 3794 (2007/10/03)

[reaction--see text] An 18-step asymmetric synthesis of the bryostatin 1 "southern hemisphere" fragment (1) has been developed. Key steps include an aldol reaction between 6 and 7 and a dehydration to establish the (E)-exocyclic alkene in 2 and a stereose
