Check Digit Verification of cas no
The CAS Registry Mumber 84857-03-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,4,8,5 and 7 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 84857-03:
(7*8)+(6*4)+(5*8)+(4*5)+(3*7)+(2*0)+(1*3)=164
164 % 10 = 4
So 84857-03-4 is a valid CAS Registry Number.

Synthetic studies on halichondrins: A new practical synthesis of the C.1-C.12 segment
Duan,Kishi
, p. 7541 - 7544 (1993)
A new practical synthesis of the C.1-C.12 halichondrin segment was achieved from L-mannonic γ-lactone (5), using osmylation, C-allylation and Michael reaction as key steps.
