2Check Digit Verification of cas no
The CAS Registry Mumber 6409-08-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,4,0 and 9 respectively; the second part has 2 digits, 0 and 8 respectively.Calculate Digit Verification of CAS Registry Number 6409-08:
(6*6)+(5*4)+(4*0)+(3*9)+(2*0)+(1*8)=91
91 % 10 = 1
So 6409-08-1 is a valid CAS Registry Number.
