195534-62-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 195534-62-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,5,5,3 and 4 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 195534-62:
(8*1)+(7*9)+(6*5)+(5*5)+(4*3)+(3*4)+(2*6)+(1*2)=164
164 % 10 = 4
So 195534-62-4 is a valid CAS Registry Number.

Sequential cyclization/silylation of enynes catalyzed by an organoyttrium complex
Molander, Gary A.,Retsch, William H.
, p. 8817 - 8825 (2007/10/03)
The organoyttrium complex Cp*2YCH3·THF (Cp* = C5Me5) has been shown to be an effective precatalyst for the selective sequential cyclization/silylation of 1,6- and 1,7-enynes. The catalyst's ability to insert the
