Check Digit Verification of cas no
The CAS Registry Mumber 133344-19-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,3,4 and 4 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 133344-19:
(8*1)+(7*3)+(6*3)+(5*3)+(4*4)+(3*4)+(2*1)+(1*9)=101
101 % 10 = 1
So 133344-19-1 is a valid CAS Registry Number.
