Check Digit Verification of cas no

The CAS Registry Mumber 91859-98-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,8,5 and 9 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 91859-98:
(7*9)+(6*1)+(5*8)+(4*5)+(3*9)+(2*9)+(1*8)=182
182 % 10 = 2
So 91859-98-2 is a valid CAS Registry Number.

Access to a Chiral Phosphine-NHC Palladium(II) Complex via the Asymmetric Hydrophosphination of Achiral Vinyl Azoles

Leung, Pak-Hing,Li, Yongxin,Pullarkat, Sumod A.,Seah, Jeffery Wee Kiong

, p. 2118 - 2122 (2021)

Enantioenriched phosphine azoles were synthesized in high yields via palladium-catalyzed asymmetric hydrophosphination with excellent yields and enantioselectivities under mild reaction conditions. One of the phosphine azoles was methylated and complexed to palladium(II) cleanly to give a chiral phosphine-NHC palladium(II) complex with excellent overall conversion.
