Check Digit Verification of cas no

The CAS Registry Mumber 857144-40-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,7,1,4 and 4 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 857144-40:
(8*8)+(7*5)+(6*7)+(5*1)+(4*4)+(3*4)+(2*4)+(1*0)=182
182 % 10 = 2
So 857144-40-2 is a valid CAS Registry Number.

Diphenylamino end-capped oligofluorenes with enhanced functional properties for blue light emission: Synthesis and structure-property relationships

Li, Zhong Hui,Wong, Man Shing,Tao, Ye,Lu, Jianping

, p. 3285 - 3293 (2005)

A novel series of monodisperse asymmetrically and symmetrically substituted diphenylamino end-capped oligofluorenes, OF(2)-NPhR, R = H or An (An = 9-anthryl) and OF(n)-NPh, n = 2-4, has been synthesized by a convergent approach using palladium-catalyzed S
