Check Digit Verification of cas no

The CAS Registry Mumber 1229407-69-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,9,4,0 and 7 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1229407-69:
(9*1)+(8*2)+(7*2)+(6*9)+(5*4)+(4*0)+(3*7)+(2*6)+(1*9)=155
155 % 10 = 5
So 1229407-69-5 is a valid CAS Registry Number.

Synthesis of trifunctional thioureas bearing 1,5-disubstituted triazole tether by Ru-catalyzed Huisgen cycloaddition

Takasu, Kiyosei,Azuma, Takumi,Takemoto, Yoshiji

, p. 2737 - 2740 (2010)

Synthesis of trifunctional thiourea catalysts tethered with a variety of functional group is described. 1,5-Triazole tether in the catalysts was constructed by ruthenium-catalyzed Huisgen cycloaddition. We demonstrate the utility of the synthetic thioureas as an asymmetric catalyst for Michal addition of nitrostyrene with cyclohexanone.
