Check Digit Verification of cas no
The CAS Registry Mumber 129230-73-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,2,3 and 0 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 129230-73:
(8*1)+(7*2)+(6*9)+(5*2)+(4*3)+(3*0)+(2*7)+(1*3)=115
115 % 10 = 5
So 129230-73-5 is a valid CAS Registry Number.
