Check Digit Verification of cas no
The CAS Registry Mumber 191805-01-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,1,8,0 and 5 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 191805-01:
(8*1)+(7*9)+(6*1)+(5*8)+(4*0)+(3*5)+(2*0)+(1*1)=133
133 % 10 = 3
So 191805-01-3 is a valid CAS Registry Number.
