Check Digit Verification of cas no
The CAS Registry Mumber 34740-32-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,4,7,4 and 0 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 34740-32:
(7*3)+(6*4)+(5*7)+(4*4)+(3*0)+(2*3)+(1*2)=104
104 % 10 = 4
So 34740-32-4 is a valid CAS Registry Number.

Silylation of 4-sydnonyllithium compounds with chlorosilanes leads to 4-sydnonylsilanes (3a-d, 5d). 5d and other bis(4-sydnonyl)silanes can also be prepared preferably by "trans-silation reaction".
