128190-45-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 128190-45-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,1,9 and 0 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 128190-45:
(8*1)+(7*2)+(6*8)+(5*1)+(4*9)+(3*0)+(2*4)+(1*5)=124
124 % 10 = 4
So 128190-45-4 is a valid CAS Registry Number.

Photochemical synthesis and thermal interconversion of mer- and fac-W(CO)3(P(OMe)3)(η4-1,5-cyclooctadiene)
Wink, Donald J.,Oh, Chang Kyeong
, p. 2403 - 2406 (2008/10/08)
Both fac and mer isomers of W(CO)3(P(OMe)3)(η4-1,5-cyclooctadiene) are formed in a photolysis reaction. They readily interconvert thermally, with the fac isomer favored by a ca. 2:1 ratio.
