121025-45-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 121025-45-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,0,2 and 5 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 121025-45:
(8*1)+(7*2)+(6*1)+(5*0)+(4*2)+(3*5)+(2*4)+(1*5)=64
64 % 10 = 4
So 121025-45-4 is a valid CAS Registry Number.

Determination of the relative and absolute stereochemistry of sphingofungins A, B, C, and D
VanMiddlesworth, Frank,Dufresne, Claude,Wincott, Francine E.,Mosley, Ralph T.,Wilson, Kenneth E.
, p. 297 - 300 (2007/10/02)
The relative and absolute stereochemistry of positions 2, 3, 4, and 5 of the recently isolated sphingofungins has been determined as 2S, 3R, 4R, 5S by spectral analysis of the rigid bicyclic derivative 5, and enzymatic hydrolysis of 4 using a 2S specific
