3Check Digit Verification of cas no
The CAS Registry Mumber 6473-06-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,4,7 and 3 respectively; the second part has 2 digits, 0 and 6 respectively.Calculate Digit Verification of CAS Registry Number 6473-06:
(6*6)+(5*4)+(4*7)+(3*3)+(2*0)+(1*6)=99
99 % 10 = 9
So 6473-06-9 is a valid CAS Registry Number.
