Check Digit Verification of cas no
The CAS Registry Mumber 812639-15-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,1,2,6,3 and 9 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 812639-15:
(8*8)+(7*1)+(6*2)+(5*6)+(4*3)+(3*9)+(2*1)+(1*5)=159
159 % 10 = 9
So 812639-15-9 is a valid CAS Registry Number.

We describe a general and efficient protocol for the synthesis of organophosphine compounds from phenols and phosphines (R2PH) via a metal-free C-O bond cleavage and C-P bond formation process. This approach exhibits broad substrate scope and excellent functional group tolerance. The synthetic utilities of this protocol were demonstrated by the synthesis of chiral ligands via the various transformations of cyano groups and their applications in asymmetric catalysis.
