948837-52-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 948837-52-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,4,8,8,3 and 7 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 948837-52:
(8*9)+(7*4)+(6*8)+(5*8)+(4*3)+(3*7)+(2*5)+(1*2)=233
233 % 10 = 3
So 948837-52-3 is a valid CAS Registry Number.
