Check Digit Verification of cas no
The CAS Registry Mumber 346-99-6 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 3,4 and 6 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 346-99:
(5*3)+(4*4)+(3*6)+(2*9)+(1*9)=76
76 % 10 = 6
So 346-99-6 is a valid CAS Registry Number.

Polyvinylpyridine, a versatile solid phase for coordinative immobilisation of palladium precatalysts - Applications in Suzuki-Miyaura reactions

The immobilisation of an oxime-based palladacycle on polyvinylpyridine (PVP) resin affords a reusable, air, moisture and thermally stable palladium precatalyst which exerts high activity in Suzuki-Miyaura reactions both in batch as well as continuous-flow processes. Evidence is presented which shows that, besides serving as an anchor for the precatalyst, PVP also acts as a scavenger for Pd particles present in solution. Georg Thieme Verlag Stuttgart.
