Check Digit Verification of cas no
The CAS Registry Mumber 134023-59-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,0,2 and 3 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 134023-59:
(8*1)+(7*3)+(6*4)+(5*0)+(4*2)+(3*3)+(2*5)+(1*9)=89
89 % 10 = 9
So 134023-59-9 is a valid CAS Registry Number.
