Check Digit Verification of cas no

The CAS Registry Mumber 1000774-49-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,0,0,7,7 and 4 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1000774-49:
(9*1)+(8*0)+(7*0)+(6*0)+(5*7)+(4*7)+(3*4)+(2*4)+(1*9)=101
101 % 10 = 1
So 1000774-49-1 is a valid CAS Registry Number.

1-(3-Methylbenzo[b]thiophen-2-yl)-2-(2-Methylindol-3-yl)Cycloal-kenes, Novel Photochromic Compounds Responding to InGaN Blue Laser

Fan, Ping,Pan, Guilan,Huang, Zhennian,Ming, Yangfu,Fan, M. G.

, p. 33 - 38 (2007/10/03)

A novel kind of photochromic compounds, the derivatives of 1-(3-Methylbenzo[b]thiophen-2-yl)-2-(2-methylindol-3-yl)cyclo-alkene was successfully synthesized. The absorption bands of the closed-forms of these compounds centered at 440 nm thus possessing the sensitivity within the wavelength range of InGaN blue laser.
