138626-63-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 138626-63-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,6,2 and 6 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 138626-63:
(8*1)+(7*3)+(6*8)+(5*6)+(4*2)+(3*6)+(2*6)+(1*3)=148
148 % 10 = 8
So 138626-63-8 is a valid CAS Registry Number.

Approaches towards the stabilization of hemiaminal function at ornithine unit of mulundocandin
Lal, Bansi,Gund, Vitthal Genbhau
, p. 1123 - 1128 (2007/10/03)
Semisynthetic modifications at position-12 (ornithine-5-position, hemiaminal function) of mulundocandin were carried out to improve its chemical stability. New carbon-carbon (C-C) and carbon-hydrogen (C-H) linkage at hemiaminal function -12 has been achieved. Lewis acid catalyzed introduction of electron rich aryl group at position-12 of mulundocandin is developed. Synthesized mulundocandin analogues were evaluated for their chemical stability and antifungal activity against C. albicans and A. fumigatus.
