Check Digit Verification of cas no

The CAS Registry Mumber 1420231-01-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,0,2,3 and 1 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1420231-01:
(9*1)+(8*4)+(7*2)+(6*0)+(5*2)+(4*3)+(3*1)+(2*0)+(1*1)=81
81 % 10 = 1
So 1420231-01-1 is a valid CAS Registry Number.

Chiral anion phase-transfer catalysis applied to the direct enantioselective fluorinative dearomatization of phenols

Phipps, Robert J.,Toste, F. Dean

supporting information, p. 1268 - 1271 (2013/03/14)

Chiral anion phase-transfer catalysis has enabled the direct and highly enantioselective fluorinative dearomatization of phenols catalyzed by a BINOL-derived phosphate. The process efficiently transforms simple, readily available phenols into fluorinated chiral small molecules bearing reactive functionality under ambient reaction conditions with high enantioselectivity. The close relationship of the products with well-studied o-quinols provides numerous avenues for synthetic elaboration and exciting opportunities for bioisosteric replacement of hydroxyl with fluorine in natural products.
