Check Digit Verification of cas no

The CAS Registry Mumber 1254470-73-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,4,4,7 and 0 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1254470-73:
(9*1)+(8*2)+(7*5)+(6*4)+(5*4)+(4*7)+(3*0)+(2*7)+(1*3)=149
149 % 10 = 9
So 1254470-73-9 is a valid CAS Registry Number.

[FeIII(F20-tpp)Cl] Is an effective catalyst for nitrene transfer reactions and animation of saturated hydrocarbons with sulfonyl and aryl azides as nitrogen source under thermal and microwave-assisted conditions

Liu, Yungen,Che, Chi-Ming

experimental part, p. 10494 - 10501 (2010/10/21)

[FeIII(F20-tpp)Cl] (F20tpp = meso- tetrakis(pentafluorophenyl)porphyrinato dianion) is an effective catalyst for imido/nitrene insertion reactions using sulfonyl and aryl azides as nitrogen source. Under thermal conditions, aziridination of aryl and alkyl alkenes (16 examples, 60-95% yields), sulfimidation of sulfides (11 examples, 76-96% yields), allylic amidation/amination of α-methylstyrenes (15 examples, 68-83% yields), and amination of saturated C-H bonds including that of cycloalkanes and adamantane (eight examples, 64-80% yields) can be accomplished by using 2 mol % [FeIII(F20- tpp)Cl] as catalyst. Under microwave irradiation conditions, the reaction time of aziridination (four examples), allylic amination (five examples), sulfimidation (two examples), and amination of saturated C-H bonds (three examples) can be reduced by up to 16fold (24-48 versus 1.5-6 h) without significantly affecting the product yield and substrate conversion.
