216966-11-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 216966-11-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,6,9,6 and 6 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 216966-11:
(8*2)+(7*1)+(6*6)+(5*9)+(4*6)+(3*6)+(2*1)+(1*1)=149
149 % 10 = 9
So 216966-11-9 is a valid CAS Registry Number.

Distal Weak Coordination of Acetamides in Ruthenium(II)-Catalyzed C?H Activation Processes

Bu, Qingqing,Rogge, Torben,Kotek, Vladislav,Ackermann, Lutz

, p. 765 - 768 (2018)

C?H activations with challenging arylacetamides were accomplished by versatile ruthenium(II) biscarboxylate catalysis. The distal C?H functionalization offers ample scope—including twofold oxidative C?H functionalizations and alkyne hydroarylations—throug

Method of using deuterated calcium channel blockers

-

Page column 20, (2010/02/04)

A method of enhancing the efficiency and increasing the duration of action of drugs (e.g. dihydropyridines and anti-bacterials) and particularly of nifedipine and penicillins wherein one or more hydrogen atoms are deuterated and wherein the deuterated drug has unexpectedly improved properties when used in much lower concentrations than unmodified drug. A method for determining the identity and bioequivalency of a new drug is also disclosed wherein the molecular and isotope structure of a new drug is determined by isotope ratio mass spectrometry and compared with the molecular and isotope structure of a known human drug.
