Check Digit Verification of cas no
The CAS Registry Mumber 129087-75-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,0,8 and 7 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 129087-75:
(8*1)+(7*2)+(6*9)+(5*0)+(4*8)+(3*7)+(2*7)+(1*5)=148
148 % 10 = 8
So 129087-75-8 is a valid CAS Registry Number.
