397851-77-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 397851-77-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,9,7,8,5 and 1 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 397851-77:
(8*3)+(7*9)+(6*7)+(5*8)+(4*5)+(3*1)+(2*7)+(1*7)=213
213 % 10 = 3
So 397851-77-3 is a valid CAS Registry Number.

Total synthesis of (-)-callystatin A
Marshall, James A.,Bourbeau, Matthew P.
, p. 2751 - 2754 (2007/10/03)
A total synthesis of the cytotoxic polyketide marine natural product callystatin A is described. The route features chiral allenylmetal additions to construct the polypropionate C15-22 segment and an sp2-sp3 Suzuki coupling to join the C1-C11 and C12-C22 subunits.
