Check Digit Verification of cas no

The CAS Registry Mumber 228115-97-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,8,1,1 and 5 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 228115-97:
(8*2)+(7*2)+(6*8)+(5*1)+(4*1)+(3*5)+(2*9)+(1*7)=127
127 % 10 = 7
So 228115-97-7 is a valid CAS Registry Number.

Synthesis studies of structural analogues of tagetitoxin: 4-O-acetyl-3- amino-1,6-anhydro-3-deoxy-D-gulose 2-phosphate

Dent, Barry R.,Furneaux, Richard H.,Gainsford, Graeme J.,Lynch, Gregory P.

, p. 6977 - 6996 (2007/10/03)

Synthetic approaches to structural analogues of tagetitoxin (1) are described. The successful route to analogue 3 (X=O) has, as a key step, protection of the cis-vicinal amino alcohol moiety of compound 7 as an N- benzylated cyclic carbamate (9). X-Ray cr
