Check Digit Verification of cas no

The CAS Registry Mumber 1031811-09-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,3,1,8,1 and 1 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1031811-09:
(9*1)+(8*0)+(7*3)+(6*1)+(5*8)+(4*1)+(3*1)+(2*0)+(1*9)=92
92 % 10 = 2
So 1031811-09-2 is a valid CAS Registry Number.

Palladium supported SBA-functionalizd 1,2-dicarboxylic acid: The first Pd-based heterogeneous synthesis of fluorenones

Mohammadkhanni, Abolfazl,Bazgir, Ayoob

, p. 28 - 36 (2018)

The first Pd-based heterogeneous homo- and cross-coupling reactions for the fluorenones synthesis are reported. The palladium supported SBA-functionalizd 1,2-dicarboxylic acid (Pd@DCA-SBA) was prepared and characterized by the FT-IR, TGA, AAS, TEM, and EDS measurements. The prepared catalyst exhibited a high performance in some homo and cross coupling reactions for the synthesis of fluorenone derivatives using 2-bromo or 2,7-dibromo fluorenone in ethanol-water as green solvent medium.
