blue.Check Digit Verification of cas no
The CAS Registry Mumber 6416-69-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,4,1 and 6 respectively; the second part has 2 digits, 6 and 9 respectively.Calculate Digit Verification of CAS Registry Number 6416-69:
(6*6)+(5*4)+(4*1)+(3*6)+(2*6)+(1*9)=99
99 % 10 = 9
So 6416-69-9 is a valid CAS Registry Number.
