27712-87-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 27712-87-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,7,7,1 and 2 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 27712-87:
(7*2)+(6*7)+(5*7)+(4*1)+(3*2)+(2*8)+(1*7)=124
124 % 10 = 4
So 27712-87-4 is a valid CAS Registry Number.

Diaminoterephthalates: Scaffolds for combinatorial chemistry
Pflantz, Rebekka,Christoffers, Jens
experimental part, p. 2200 - 2209 (2009/09/25)
2,5-Diaminoterephthalates that possess four points of diversification are introduced as new scaffolds for combinatorial chemistry. A straightforward synthesis of an orthogonally protected platform compound was developed. This platform was transformed by s
