Check Digit Verification of cas no
The CAS Registry Mumber 147752-52-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,7,7,5 and 2 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 147752-52:
(8*1)+(7*4)+(6*7)+(5*7)+(4*5)+(3*2)+(2*5)+(1*2)=151
151 % 10 = 1
So 147752-52-1 is a valid CAS Registry Number.
