Check Digit Verification of cas no
The CAS Registry Mumber 133156-38-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,1,5 and 6 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 133156-38:
(8*1)+(7*3)+(6*3)+(5*1)+(4*5)+(3*6)+(2*3)+(1*8)=104
104 % 10 = 4
So 133156-38-4 is a valid CAS Registry Number.
