Check Digit Verification of cas no

The CAS Registry Mumber 1153285-12-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,5,3,2,8 and 5 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1153285-12:
(9*1)+(8*1)+(7*5)+(6*3)+(5*2)+(4*8)+(3*5)+(2*1)+(1*2)=131
131 % 10 = 1
So 1153285-12-1 is a valid CAS Registry Number.

Rhodium-Catalyzed Double Alkyl-Oxygen Bond Cleavage: An Alkyl Transfer Reaction from Bis/Tris(o-alkyloxyphenyl)phosphine to Aryl Acids

Zhou, Hui,Zhang, Jinlong,Yang, Huameng,Xia, Chungu,Jiang, Gaoxi

supporting information, p. 3406 - 3412 (2016/10/21)

An unprecedented rhodium-catalyzed selective cleavage of double alkyl-oxygen bonds of bis/tris(o-alkyloxyphenyl)phosphine has been realized, in which P atom functions as a directing group and simple aryl acids are the methyl group acceptor to provide methyl esters and a quaternary phosphonium salt. The preliminary mechanism was investigated via an 18O labeling experiment and stoichiometric reaction between a Rh-A crystal and an aromatic acid.
