Check Digit Verification of cas no
The CAS Registry Mumber 121819-13-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,8,1 and 9 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 121819-13:
(8*1)+(7*2)+(6*1)+(5*8)+(4*1)+(3*9)+(2*1)+(1*3)=104
104 % 10 = 4
So 121819-13-4 is a valid CAS Registry Number.
