541534-89-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 541534-89-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,4,1,5,3 and 4 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 541534-89:
(8*5)+(7*4)+(6*1)+(5*5)+(4*3)+(3*4)+(2*8)+(1*9)=148
148 % 10 = 8
So 541534-89-8 is a valid CAS Registry Number.
