142720-35-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 142720-35-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,7,2 and 0 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 142720-35:
(8*1)+(7*4)+(6*2)+(5*7)+(4*2)+(3*0)+(2*3)+(1*5)=102
102 % 10 = 2
So 142720-35-2 is a valid CAS Registry Number.
