Check Digit Verification of cas no
The CAS Registry Mumber 155943-44-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,5,9,4 and 3 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 155943-44:
(8*1)+(7*5)+(6*5)+(5*9)+(4*4)+(3*3)+(2*4)+(1*4)=155
155 % 10 = 5
So 155943-44-5 is a valid CAS Registry Number.
