152485-80-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 152485-80-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,2,4,8 and 5 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 152485-80:
(8*1)+(7*5)+(6*2)+(5*4)+(4*8)+(3*5)+(2*8)+(1*0)=138
138 % 10 = 8
So 152485-80-8 is a valid CAS Registry Number.
