142052-70-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 142052-70-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,0,5 and 2 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 142052-70:
(8*1)+(7*4)+(6*2)+(5*0)+(4*5)+(3*2)+(2*7)+(1*0)=88
88 % 10 = 8
So 142052-70-8 is a valid CAS Registry Number.

A new process for preparing dialdehydes by catalytic oxidation of cyclic olefins with aqueous hydrogen peroxide
Deng,Xu,Chen,Jiang
, p. 3503 - 3514 (1992)
Dialdehydes were prepared by the reaction between cyclic olefins and aqueous hydrogen peroxide catalyzed by tungstic acid. Glutaraldehyde and adipaldehyde were synthesized by this method with good yield. Several different conditions were tested.
