138450-27-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 138450-27-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,4,5 and 0 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 138450-27:
(8*1)+(7*3)+(6*8)+(5*4)+(4*5)+(3*0)+(2*2)+(1*7)=128
128 % 10 = 8
So 138450-27-8 is a valid CAS Registry Number.

Optically active triarylboranes: Synthesis and stereoisomerization of ethano-bridged triarylboranes
Okada, Keiji,Inokawa, Haruki,Oda, Masaji
, p. 6363 - 6366 (2007/10/02)
Ethano-bridged triarylboranes 1a-c were synthesized. The boranes 1b and lc were resolved into optically pure form (the first example of optical resolution of triarylboranes). The activation parameters of the racemization were determined.
