Check Digit Verification of cas no
The CAS Registry Mumber 200122-07-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,0,1,2 and 2 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 200122-07:
(8*2)+(7*0)+(6*0)+(5*1)+(4*2)+(3*2)+(2*0)+(1*7)=42
42 % 10 = 2
So 200122-07-2 is a valid CAS Registry Number.

Synthesis of archaebacterial lipid C20 chirons
Berkowitz, William F.,Yanzhong, Wu
, p. 8141 - 8144 (2007/10/03)
Archaebacterial lipid C20 chirons were synthesized by cross-coupling optically active C10 'dimer' units prepared from hydroxyester 7. Vitamin E (C15) side chain was similarly constructed.
