Check Digit Verification of cas no
The CAS Registry Mumber 91134-85-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,1,3 and 4 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 91134-85:
(7*9)+(6*1)+(5*1)+(4*3)+(3*4)+(2*8)+(1*5)=119
119 % 10 = 9
So 91134-85-9 is a valid CAS Registry Number.
