5634-23-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 5634-23-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,6,3 and 4 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 5634-23:
(6*5)+(5*6)+(4*3)+(3*4)+(2*2)+(1*3)=91
91 % 10 = 1
So 5634-23-1 is a valid CAS Registry Number.

HIGH-YIELD CATALYTIC METATHESIS OF ALKENYL TOSYLATES WITH APPLICATIONS IN ORGANIC SYNTHESIS
Daly, Daniel G.,McKervey, M. Anthony
, p. 2997 - 2998 (2007/10/02)
Alkenyl tosylates of the type RCH=CH(CH2)nOTs undergo metathesis using a WCl6-Me3SnCl catalyst system, producing difunctionalised alkenes of the type TsO(CH2)nCH=CH(CH2)nOTs (n=7,8, and 9); examples of the use of
