Check Digit Verification of cas no

The CAS Registry Mumber 916988-26-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,1,6,9,8 and 8 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 916988-26:
(8*9)+(7*1)+(6*6)+(5*9)+(4*8)+(3*8)+(2*2)+(1*6)=226
226 % 10 = 6
So 916988-26-6 is a valid CAS Registry Number.

Synthesis and crystallographic analysis of benzophenone derivatives-The potential anti-inflammatory agents

Venu,Shashikanth,Khanum,Naveen,Firdouse, Aiysha,Sridhar,Shashidhara Prasad

, p. 3505 - 3514 (2008/02/07)

Fries rearrangement of substituted phenyl benzoates 1a-j to substituted hydroxy benzophenones 2a-j was achieved in excellent yield. Further benzoylation of 2a-j to benzoyloxy benzophenones 4a-n, a benzophenone analogue was achieved in good yield. All the newly synthesized compounds were evaluated for their anti-inflammatory activity and were compared with standard drugs. Out of the compounds studied, the compounds 4c, 4e, 4g, 4h and 4k with chloro and methyl substituents at para position showed more potent activity than the standard drugs at all doses tested.
