Check Digit Verification of cas no
The CAS Registry Mumber 1542081-05-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,4,2,0,8 and 1 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1542081-05:
(9*1)+(8*5)+(7*4)+(6*2)+(5*0)+(4*8)+(3*1)+(2*0)+(1*5)=129
129 % 10 = 9
So 1542081-05-9 is a valid CAS Registry Number.
