Check Digit Verification of cas no
The CAS Registry Mumber 6272-71-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,2,7 and 2 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 6272-71:
(6*6)+(5*2)+(4*7)+(3*2)+(2*7)+(1*1)=95
95 % 10 = 5
So 6272-71-5 is a valid CAS Registry Number.
