101582-57-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 101582-57-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,1,5,8 and 2 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 101582-57:
(8*1)+(7*0)+(6*1)+(5*5)+(4*8)+(3*2)+(2*5)+(1*7)=94
94 % 10 = 4
So 101582-57-4 is a valid CAS Registry Number.

Transition-metal-free synthesis of aromatic amines via the reaction of benzynes with isocyanates
Seo, Jeong Hoon,Ko, Haye Min
, p. 671 - 674 (2018)
An unexpected reaction between benzynes and isocyanates to generate aromatic amines has been developed under transition-metal-free conditions. The in situ prepared anions formed through cleavage of the N–C bond in isocyanates, reacted with aryne precursor
