Check Digit Verification of cas no
The CAS Registry Mumber 129958-80-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,9,5 and 8 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 129958-80:
(8*1)+(7*2)+(6*9)+(5*9)+(4*5)+(3*8)+(2*8)+(1*0)=181
181 % 10 = 1
So 129958-80-1 is a valid CAS Registry Number.
