Check Digit Verification of cas no
The CAS Registry Mumber 6598-63-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,5,9 and 8 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 6598-63:
(6*6)+(5*5)+(4*9)+(3*8)+(2*6)+(1*3)=136
136 % 10 = 6
So 6598-63-6 is a valid CAS Registry Number.
