72729-16-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 72729-16-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,2,7,2 and 9 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 72729-16:
(7*7)+(6*2)+(5*7)+(4*2)+(3*9)+(2*1)+(1*6)=139
139 % 10 = 9
So 72729-16-9 is a valid CAS Registry Number.

Total synthesis of (-)-maysine
Meyers,Babiak,Campbell,et al.
, p. 5015 - 5024 (2007/10/02)
A convergent synthesis of the natural macrocycle (-)-maysine (3) has been accomplished involving only a single separation of epimers at C-10. The scheme involved the preparation of three major fragments: (a) the western zone, 4; (b) the southern zone, 6;
