Check Digit Verification of cas no

The CAS Registry Mumber 153034-25-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,3,0,3 and 4 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 153034-25:
(8*1)+(7*5)+(6*3)+(5*0)+(4*3)+(3*4)+(2*2)+(1*5)=94
94 % 10 = 4
So 153034-25-4 is a valid CAS Registry Number.

Steric acceleration of intramolecular cycloaddition reactions

Orlek, Barry S.,Sammes, Peter G.,Weller, David J.

, p. 8179 - 8194 (2007/10/02)

Use of conformational constraints, induced by different ortho-substituents in 1-allyloxy-2-(substituted)methylbenzenes, where the substituent is a 1,3-dipole such as the azide or 3-oxidopyridinium group, can be employed to accelerate the 1,3-dipolar cycloaddition reaction. In this manner cycloadditions that otherwise do not proceed can be forced to react.
