Check Digit Verification of cas no
The CAS Registry Mumber 61951-82-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,1,9,5 and 1 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 61951-82:
(7*6)+(6*1)+(5*9)+(4*5)+(3*1)+(2*8)+(1*2)=134
134 % 10 = 4
So 61951-82-4 is a valid CAS Registry Number.
