Check Digit Verification of cas no
The CAS Registry Mumber 489417-68-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,8,9,4,1 and 7 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 489417-68:
(8*4)+(7*8)+(6*9)+(5*4)+(4*1)+(3*7)+(2*6)+(1*8)=207
207 % 10 = 7
So 489417-68-7 is a valid CAS Registry Number.
