Check Digit Verification of cas no
The CAS Registry Mumber 61951-86-8 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 6 respectively.
Calculate Digit Verification of CAS Registry Number 61951-86:
(7*6)+(6*1)+(5*9)+(4*5)+(3*1)+(2*8)+(1*6)=138
138 % 10 = 8
So 61951-86-8 is a valid CAS Registry Number.
