Check Digit Verification of cas no
The CAS Registry Mumber 145980-63-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,5,9,8 and 0 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 145980-63:
(8*1)+(7*4)+(6*5)+(5*9)+(4*8)+(3*0)+(2*6)+(1*3)=158
158 % 10 = 8
So 145980-63-8 is a valid CAS Registry Number.
