1265228-11-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1265228-11-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,5,2,2 and 8 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1265228-11:
(9*1)+(8*2)+(7*6)+(6*5)+(5*2)+(4*2)+(3*8)+(2*1)+(1*1)=142
142 % 10 = 2
So 1265228-11-2 is a valid CAS Registry Number.

Novel dispirobifluorenes and indeno-spirobifluorenes: Syntheses and properties
Shi, Yingbo,Liu, Qiancai,Wu, Guohong,Rong, Lingling,Tang, Jie
, p. 1201 - 1209 (2011/03/22)
Novel indeno-spirobifluorene and dispirobifluorene derivatives were synthesized and characterized. Their two positional isomers were unambiguously determined by X-ray crystallography. Preliminary investigations indicated that these indeno-spirobifluorene
