Check Digit Verification of cas no
The CAS Registry Mumber 71998-90-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,9,9 and 8 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 71998-90:
(7*7)+(6*1)+(5*9)+(4*9)+(3*8)+(2*9)+(1*0)=178
178 % 10 = 8
So 71998-90-8 is a valid CAS Registry Number.
