101533-70-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 101533-70-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,1,5,3 and 3 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 101533-70:
(8*1)+(7*0)+(6*1)+(5*5)+(4*3)+(3*3)+(2*7)+(1*0)=74
74 % 10 = 4
So 101533-70-4 is a valid CAS Registry Number.

Hanack, Michael,Rieth, Robert
, p. 1487 - 1489 (2007/10/02)
Cyclodeca-1,3-dien-5-yn-1-yl trifluoromethanesulphonate (2) has been synthesized and solvolysed in different solvent systems to give cyclized aromatic products exclusively, which are formed mainly via an aryl cation (5) intermediate.
