Check Digit Verification of cas no
The CAS Registry Mumber 79897-70-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,9,8,9 and 7 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 79897-70:
(7*7)+(6*9)+(5*8)+(4*9)+(3*7)+(2*7)+(1*0)=214
214 % 10 = 4
So 79897-70-4 is a valid CAS Registry Number.
