19559-24-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 19559-24-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,5,5 and 9 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 19559-24:
(7*1)+(6*9)+(5*5)+(4*5)+(3*9)+(2*2)+(1*4)=141
141 % 10 = 1
So 19559-24-1 is a valid CAS Registry Number.

The Biosynthesis of Xanthocillin-X Monomethyl Ether in Dichotomomyces cejpii. Experiments on the Origin of the Isocyanide Carbon Atoms
Cable, Karl M.,Herbert, Richard B.,Knaggs, Andrew R.,Mann, Jonathan
, p. 595 - 599 (2007/10/02)
Precursor feeding experiments establish that the isocyanide groups in xanthocillin-X monomethyl ether (XME) 1 do not originate from (i) compounds associated with C1-tetrahydrofolate metabolism; (ii) the ureido group of citrulline, carbamoyl pho
