869808-53-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 869808-53-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,6,9,8,0 and 8 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 869808-53:
(8*8)+(7*6)+(6*9)+(5*8)+(4*0)+(3*8)+(2*5)+(1*3)=237
237 % 10 = 7
So 869808-53-7 is a valid CAS Registry Number.

Unusual tandem alkynylation and trans-hydrosilylation to form oxasilacyclopentenes
Maifeld, Sarah V.,Lee, Daesung
, p. 4995 - 4998 (2007/10/03)
(Chemical Equation Presented) An unusual tandem reaction sequence to form oxasilacyclopentenes from carbonyls and alkynylsilanes in the presence of a catalytic amount of nucleophilic initiator has been discovered. The reaction proceeds readily at room tem
