Check Digit Verification of cas no

The CAS Registry Mumber 1201698-58-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,0,1,6,9 and 8 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1201698-58:
(9*1)+(8*2)+(7*0)+(6*1)+(5*6)+(4*9)+(3*8)+(2*5)+(1*8)=139
139 % 10 = 9
So 1201698-58-9 is a valid CAS Registry Number.

Enantioselective Friedel-Crafts alkylation of pyrroles catalyzed by PYBOX-DIPH-Zn(II) complexes

Singh, Pradeep K.,Singh, Vinod K.

supporting information; scheme or table, p. 80 - 83 (2010/03/03)

Chemical Equation Presented A highly enantioselective Friedel-Crafts alkylation of pyrroles with 2-enoylpyridine 2-oxides catalyzed by chiral PYBOX-DIPH-Zn(II) complexes has been developed. The catalyst offers substantial substrate scope and furnished alkylated pyrroles in excellent yields (up to 99%) and enantioselectivities (up to >99% ee).
