Check Digit Verification of cas no
The CAS Registry Mumber 77861-05-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,8,6 and 1 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 77861-05:
(7*7)+(6*7)+(5*8)+(4*6)+(3*1)+(2*0)+(1*5)=163
163 % 10 = 3
So 77861-05-3 is a valid CAS Registry Number.
