Check Digit Verification of cas no
The CAS Registry Mumber 78998-63-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,9,9 and 8 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 78998-63:
(7*7)+(6*8)+(5*9)+(4*9)+(3*8)+(2*6)+(1*3)=217
217 % 10 = 7
So 78998-63-7 is a valid CAS Registry Number.
