Check Digit Verification of cas no

The CAS Registry Mumber 1246890-40-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,6,8,9 and 0 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1246890-40:
(9*1)+(8*2)+(7*4)+(6*6)+(5*8)+(4*9)+(3*0)+(2*4)+(1*0)=173
173 % 10 = 3
So 1246890-40-3 is a valid CAS Registry Number.

Liu, Xin-Hua,Liu, Jin-Xin,Bai, Lin-Shan,Lan, Guo-Lin,Pan, Chu-Xiou

, p. 487 - 490 (2010)

Seven novel 6-(1-acetyl-3-methyl-4,5-dihydro-1H-pyrazol-5-yl)-2-amino-4- substituted-phenyl-4H-chromene-3-carbonitrile derivatives were synthesized and characterized by ESI-MS, 1H NMR and 13C NMR. All of the compounds have been screened for their antibact
