Check Digit Verification of cas no
The CAS Registry Mumber 142731-35-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,7,3 and 1 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 142731-35:
(8*1)+(7*4)+(6*2)+(5*7)+(4*3)+(3*1)+(2*3)+(1*5)=109
109 % 10 = 9
So 142731-35-9 is a valid CAS Registry Number.
