887751-33-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 887751-33-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,8,7,7,5 and 1 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 887751-33:
(8*8)+(7*8)+(6*7)+(5*7)+(4*5)+(3*1)+(2*3)+(1*3)=229
229 % 10 = 9
So 887751-33-9 is a valid CAS Registry Number.

Total synthesis of (-)-dictyostatin
O'Neil, Gregory W.,Phillips, Andrew J.
, p. 5340 - 5341 (2007/10/03)
A convergent total synthesis of dictyostatin is described. Key features of the synthesis include the use of titanium-mediated cyclizations of (silyloxy)enynes for the synthesis of stereotriads, a subunit coupling by metathesis, and macrocyclization by int
