80677-32-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 80677-32-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,6,7 and 7 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 80677-32:
(7*8)+(6*0)+(5*6)+(4*7)+(3*7)+(2*3)+(1*2)=143
143 % 10 = 3
So 80677-32-3 is a valid CAS Registry Number.

MECHANISMEN BEI REAKTIONEN VON CHIRALEN PHOSPHANEN MIT ELEKTRONEGATIV-SUBSTITUIERTEN STICKSTOFFVERBINDUNGEN
Heesing, A.,Steinkamp, H.
, p. 3827 - 3828 (1981)
In the reaction of the chiral phosphane 1 with electronegative substituted nitrogen compounds both a SN (N) mechanism and nucleophilic attack on the nitrogen substituent occur depending on the nature of the nucleofuge.
