Check Digit Verification of cas no
The CAS Registry Mumber 129855-25-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,8,5 and 5 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 129855-25:
(8*1)+(7*2)+(6*9)+(5*8)+(4*5)+(3*5)+(2*2)+(1*5)=160
160 % 10 = 0
So 129855-25-0 is a valid CAS Registry Number.
