Check Digit Verification of cas no
The CAS Registry Mumber 324541-89-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,2,4,5,4 and 1 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 324541-89:
(8*3)+(7*2)+(6*4)+(5*5)+(4*4)+(3*1)+(2*8)+(1*9)=131
131 % 10 = 1
So 324541-89-1 is a valid CAS Registry Number.
