1315323-57-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1315323-57-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,1,5,3,2 and 3 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1315323-57:
(9*1)+(8*3)+(7*1)+(6*5)+(5*3)+(4*2)+(3*3)+(2*5)+(1*7)=119
119 % 10 = 9
So 1315323-57-9 is a valid CAS Registry Number.

supporting information; experimental part, p. 4352 - 4355 (2011/10/08)
A highly convergent synthesis of the pyridine core of the thiopeptide antibiotic cyclothiazomycin has been developed based on a [2 + 2 + 2] cyclotrimerization key step. The regioselective assembly of the heterocyclic center of this important class of anti
