Check Digit Verification of cas no
The CAS Registry Mumber 87251-56-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,2,5 and 1 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 87251-56:
(7*8)+(6*7)+(5*2)+(4*5)+(3*1)+(2*5)+(1*6)=147
147 % 10 = 7
So 87251-56-7 is a valid CAS Registry Number.
