Check Digit Verification of cas no

The CAS Registry Mumber 349542-30-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,4,9,5,4 and 2 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 349542-30:
(8*3)+(7*4)+(6*9)+(5*5)+(4*4)+(3*2)+(2*3)+(1*0)=159
159 % 10 = 9
So 349542-30-9 is a valid CAS Registry Number.

Silica gel-mediated amide bond formation: An environmentally benign method for liquid-phase synthesis and cytotoxic activities of amides

scheme or table, p. 307 - 310 (2010/11/18)

An efficient, functional group tolerable, and environmentally benign process for the synthesis of amides was developed. No activation reagents or scavengers are required in this process. Purification of desired compounds is easy, rapid, and cost-effective. This protocol provides an alternative for the combinatorial liquid-phase synthesis of amide libraries for drug discovery. By this method, a number of amides were prepared and evaluated in vitro against a panel of human tumor cell lines. Cinnamic amide IV-4 was found to be the most potent compound synthesized against four human tumor cell lines.
