Check Digit Verification of cas no
The CAS Registry Mumber 928005-87-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,2,8,0,0 and 5 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 928005-87:
(8*9)+(7*2)+(6*8)+(5*0)+(4*0)+(3*5)+(2*8)+(1*7)=172
172 % 10 = 2
So 928005-87-2 is a valid CAS Registry Number.

Discriminating between the six isomers of dicaffeoylquinic acid by LC-MSn
Clifford, Michael N.,Knight, Susan,Kuhnert, Nikolai
, p. 3821 - 3832 (2005)
The fragmentation behavior of all six dicaffeoylquinic acids (diCQA) has been investigated using LC-MS4. It is possible to discriminate between each of the isomers including those for which commercial standards are not available. For diCQA, the
