Check Digit Verification of cas no
The CAS Registry Mumber 524952-47-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,2,4,9,5 and 2 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 524952-47:
(8*5)+(7*2)+(6*4)+(5*9)+(4*5)+(3*2)+(2*4)+(1*7)=164
164 % 10 = 4
So 524952-47-4 is a valid CAS Registry Number.
