Check Digit Verification of cas no
The CAS Registry Mumber 158980-56-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,8,9,8 and 0 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 158980-56:
(8*1)+(7*5)+(6*8)+(5*9)+(4*8)+(3*0)+(2*5)+(1*6)=184
184 % 10 = 4
So 158980-56-4 is a valid CAS Registry Number.
