Check Digit Verification of cas no

The CAS Registry Mumber 113128-26-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,3,1,2 and 8 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 113128-26:
(8*1)+(7*1)+(6*3)+(5*1)+(4*2)+(3*8)+(2*2)+(1*6)=80
80 % 10 = 0
So 113128-26-0 is a valid CAS Registry Number.

Synthesis of lutetium(iii)-porphyrin complexes: old problems and new excellent conditions found

Kalota, Bartosz,Mikus, Agnieszka,Ostrowski, Stanis?aw

, p. 9899 - 9902 (2016)

A convenient method for the preparation of very attractive and almost unknown lutetium(iii)-porphyrins was developed. Systematic investigations involving a broad spectrum of solvents (DMF, TCB, imidazole, sulfolane, and a CHCl3/MeOH mixture), as well as studies concerning the influence of temperature and the reaction time on the yield, were performed. Under the optimized experimental conditions found within the study for [5,10,15,20-tetraphenylporphyrinato]lutetium(iii) chloride (sulfolane, reflux, 0.5 h; 88% yield), the synthesis of some other more complex derivatives was demonstrated.
