Check Digit Verification of cas no

The CAS Registry Mumber 304648-05-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,0,4,6,4 and 8 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 304648-05:
(8*3)+(7*0)+(6*4)+(5*6)+(4*4)+(3*8)+(2*0)+(1*5)=123
123 % 10 = 3
So 304648-05-3 is a valid CAS Registry Number.

Modified reaction conditions to achieve high regioselectivity in the two component synthesis of 1,5-diarylpyrazoles

Singh, Sunil K.,Srinivasa Reddy,Shivaramakrishna,Kavitha,Vasudev,Babu, J. Moses,Sivalakshmidevi,Rao, Y. Koteswar

, p. 7679 - 7682 (2004)

The factors affecting regioselectivity during the formation of 1,5-diarylpyrazoles from aryl hydrazines and 1,3-diketones are identified and the regioisomers were characterized by 1D NOESY, LC-NMR and X-ray analyses. A simple alteration in the usual react
