Check Digit Verification of cas no
The CAS Registry Mumber 46902-08-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,6,9,0 and 2 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 46902-08:
(7*4)+(6*6)+(5*9)+(4*0)+(3*2)+(2*0)+(1*8)=123
123 % 10 = 3
So 46902-08-3 is a valid CAS Registry Number.

Efficient Bimetallic Catalysis of Nitrile Hydration to Amides with a Simple Pd(OAc)2/Lewis Acid Catalyst at Ambient Temperature

Transition-metal-catalyzed nitrile hydration is an atom-economic method for the synthesis of various amides. This work demonstrates for the first time that the addition of non-redox metal ions like Sc3+ dramatically accelerate the hydration of various nitriles to amides at ambient temperature with the simple Pd(OAc)2 salt as catalyst, whereas the reactions with Pd(OAc)2 alone were very sluggish. The formation of a heterobimetallic PdII/ScIII species has been proposed as the key species for the hydration that demonstrates a bimetallic synergistic effect in this process.
