Check Digit Verification of cas no
The CAS Registry Mumber 1656-71-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,5 and 6 respectively; the second part has 2 digits, 7 and 1 respectively.Calculate Digit Verification of CAS Registry Number 1656-71:
(6*1)+(5*6)+(4*5)+(3*6)+(2*7)+(1*1)=89
89 % 10 = 9
So 1656-71-9 is a valid CAS Registry Number.
