Check Digit Verification of cas no
The CAS Registry Mumber 52171-94-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,2,1,7 and 1 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 52171-94:
(7*5)+(6*2)+(5*1)+(4*7)+(3*1)+(2*9)+(1*4)=105
105 % 10 = 5
So 52171-94-5 is a valid CAS Registry Number.
