Check Digit Verification of cas no
The CAS Registry Mumber 198020-05-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,8,0,2 and 0 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 198020-05:
(8*1)+(7*9)+(6*8)+(5*0)+(4*2)+(3*0)+(2*0)+(1*5)=132
132 % 10 = 2
So 198020-05-2 is a valid CAS Registry Number.
