Check Digit Verification of cas no
The CAS Registry Mumber 883559-75-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,8,3,5,5 and 9 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 883559-75:
(8*8)+(7*8)+(6*3)+(5*5)+(4*5)+(3*9)+(2*7)+(1*5)=229
229 % 10 = 9
So 883559-75-9 is a valid CAS Registry Number.

The total synthesis of pamamycin-607. Part 2: Synthesis of the C6-C18 domain
Fraser, Benjamin H.,Mulder, Roger J.,Perlmutter, Patrick
, p. 2857 - 2867 (2007/10/03)
Synthesis of the C6-C18 domain of pamamycin-607 was achieved in ten steps and 7% overall yield from commercially available d-norvaline. The key asymmetric transformations included a Paterson anti aldol addition, an anti selective reduction of the resultan
