Check Digit Verification of cas no
The CAS Registry Mumber 18113-13-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,1,1 and 3 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 18113-13:
(7*1)+(6*8)+(5*1)+(4*1)+(3*3)+(2*1)+(1*3)=78
78 % 10 = 8
So 18113-13-8 is a valid CAS Registry Number.

Efficient 11C-carbonylation of isolated aryl palladium complexes for PET: Application to challenging radiopharmaceutical synthesis

We describe the successful implementation of palladium-aryl oxidative addition complexes as stoichiometric reagents in carbonylation reactions with 11CO to produce structurally challenging, pharmaceutically relevant compounds. This method enables the first 11C-carbonyl labeling of an approved PET tracer, [11C]raclopride, for the dopamine D2/D3 receptor by carbonylation with excellent radiochemical purity and yield. Two other molecules, [11C]olaparib and [11C]JNJ 31020028, were efficiently labeled in this manner. The technique distinguishes itself from existing methods by the markedly improved purity profiles of the tracer molecules produced and provides access to complex structures in synthetically useful yields, hereby offering a viable alternative to other 11C-labeling strategies.
