Check Digit Verification of cas no
The CAS Registry Mumber 455934-69-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,5,5,9,3 and 4 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 455934-69:
(8*4)+(7*5)+(6*5)+(5*9)+(4*3)+(3*4)+(2*6)+(1*9)=187
187 % 10 = 7
So 455934-69-7 is a valid CAS Registry Number.
