212118-80-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 212118-80-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,2,1,1 and 8 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 212118-80:
(8*2)+(7*1)+(6*2)+(5*1)+(4*1)+(3*8)+(2*8)+(1*0)=84
84 % 10 = 4
So 212118-80-4 is a valid CAS Registry Number.

Combinatorial libraries based on a novel and readily accessible 'centroid' scaffold

A convenient large-scale preparation of the trifunctional acid 1 has been developed. This acid serves as a useful scaffold for construction of combinatorial libraries incorporating three variable elements in a centro- symmetric array.
