Check Digit Verification of cas no
The CAS Registry Mumber 77970-89-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,9,7 and 0 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 77970-89:
(7*7)+(6*7)+(5*9)+(4*7)+(3*0)+(2*8)+(1*9)=189
189 % 10 = 9
So 77970-89-9 is a valid CAS Registry Number.
