159227-23-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 159227-23-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,9,2,2 and 7 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 159227-23:
(8*1)+(7*5)+(6*9)+(5*2)+(4*2)+(3*7)+(2*2)+(1*3)=143
143 % 10 = 3
So 159227-23-3 is a valid CAS Registry Number.

, p. 2167 - 2176 (1994)
On activation with Me3NO the tetrahydrido-tetranuclear cluster 1 underwent reaction with cyclohexa-1,3-diene in CH2Cl2 under ambient conditions to give, as the major products, the four organometallic clusters 3
