Check Digit Verification of cas no
The CAS Registry Mumber 108324-57-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,8,3,2 and 4 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 108324-57:
(8*1)+(7*0)+(6*8)+(5*3)+(4*2)+(3*4)+(2*5)+(1*7)=108
108 % 10 = 8
So 108324-57-8 is a valid CAS Registry Number.
