4Check Digit Verification of cas no
The CAS Registry Mumber 6449-81-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,4,4 and 9 respectively; the second part has 2 digits, 8 and 1 respectively.Calculate Digit Verification of CAS Registry Number 6449-81:
(6*6)+(5*4)+(4*4)+(3*9)+(2*8)+(1*1)=116
116 % 10 = 6
So 6449-81-6 is a valid CAS Registry Number.
