Check Digit Verification of cas no
The CAS Registry Mumber 5858-53-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,8,5 and 8 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 5858-53:
(6*5)+(5*8)+(4*5)+(3*8)+(2*5)+(1*3)=127
127 % 10 = 7
So 5858-53-7 is a valid CAS Registry Number.
