Check Digit Verification of cas no
The CAS Registry Mumber 201812-19-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,1,8,1 and 2 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 201812-19:
(8*2)+(7*0)+(6*1)+(5*8)+(4*1)+(3*2)+(2*1)+(1*9)=83
83 % 10 = 3
So 201812-19-3 is a valid CAS Registry Number.
