Check Digit Verification of cas no

The CAS Registry Mumber 1446770-93-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,4,6,7,7 and 0 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1446770-93:
(9*1)+(8*4)+(7*4)+(6*6)+(5*7)+(4*7)+(3*0)+(2*9)+(1*3)=189
189 % 10 = 9
So 1446770-93-9 is a valid CAS Registry Number.

Highly Enantiospecific Borylation for Chiral α-Amino Tertiary Boronic Esters

Qi, Qingqing,Yang, Xuena,Fu, Xiaoping,Xu, Shiqing,Negishi, Ei-ichi

, p. 15138 - 15142 (2018)

Herein we report a highly efficient and enantiospecific borylation method to synthesize a wide range of enantiopure (>99 % ee) α-amino tertiary boronic esters. The configurationally stable α-N-Boc substituted tertiary organolithium species and pinacolborane (HBpin) underwent enantiospecific borylation at ?78 °C with the formation of a new stereogenic C?B bond. This reaction has a broad scope, enabling the synthesis of various α-amino tertiary boronic esters in excellent yields and, importantly, with universally excellent enantiospecificity (>99 % es) and complete retention of configuration.
