Check Digit Verification of cas no

The CAS Registry Mumber 155939-99-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,5,9,3 and 9 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 155939-99:
(8*1)+(7*5)+(6*5)+(5*9)+(4*3)+(3*9)+(2*9)+(1*9)=184
184 % 10 = 4
So 155939-99-4 is a valid CAS Registry Number.

Ruthenium(II)-catalyzed C-H functionalizations on benzoic acids with aryl, alkenyl and alkynyl halides by weak-: O -coordination

Mei, Ruhuai,Zhu, Cuiju,Ackermann, Lutz

, p. 13171 - 13174 (2016)

C-H arylations of weakly coordinating benzoic acids were achieved by versatile ruthenium(ii) catalysis with ample substrate scope. Thus, user-friendly ruthenium(ii) biscarboxylate complexes modified with tricyclohexylphosphine enabled C-H functionalizations with aryl electrophiles. The unique versatility of the ruthenium(ii) catalysis manifold was reflected by facilitating effective C-H activations with aryl, alkenyl and alkynyl halides.
