Check Digit Verification of cas no

The CAS Registry Mumber 1290594-04-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,9,0,5,9 and 4 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1290594-04:
(9*1)+(8*2)+(7*9)+(6*0)+(5*5)+(4*9)+(3*4)+(2*0)+(1*4)=165
165 % 10 = 5
So 1290594-04-5 is a valid CAS Registry Number.

Synthesis and characterization of novel guanidine ligands featuring biphenyl or binaphthyl backbones

Maronna, Astrid,Bindewald, Elvira,Kaifer, Elisabeth,Wadepohl, Hubert,Himmel, Hans-Joerg

experimental part, p. 1302 - 1314 (2011/06/10)

In this paper we report on the synthesis and characterization of several new 2,2′-bisguanidino-1,1′-biphenyl and -binaphthyl ligands as well as the electron donor 3,3′,4,4′-tetrakis(tetramethylguanidino)-1, 1′-biphenyl. Chiral bisguanidine ligands were pr
