6-7Check Digit Verification of cas no
The CAS Registry Mumber 61969-35-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,1,9,6 and 9 respectively; the second part has 2 digits, 3 and 5 respectively.Calculate Digit Verification of CAS Registry Number 61969-35:
(7*6)+(6*1)+(5*9)+(4*6)+(3*9)+(2*3)+(1*5)=155
155 % 10 = 5
So 61969-35-5 is a valid CAS Registry Number.
