Check Digit Verification of cas no
The CAS Registry Mumber 6598-56-7 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, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 6598-56:
(6*6)+(5*5)+(4*9)+(3*8)+(2*5)+(1*6)=137
137 % 10 = 7
So 6598-56-7 is a valid CAS Registry Number.
