Check Digit Verification of cas no
The CAS Registry Mumber 5236-71-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,2,3 and 6 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 5236-71:
(6*5)+(5*2)+(4*3)+(3*6)+(2*7)+(1*1)=85
85 % 10 = 5
So 5236-71-5 is a valid CAS Registry Number.
