Check Digit Verification of cas no
The CAS Registry Mumber 182913-54-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,2,9,1 and 3 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 182913-54:
(8*1)+(7*8)+(6*2)+(5*9)+(4*1)+(3*3)+(2*5)+(1*4)=148
148 % 10 = 8
So 182913-54-8 is a valid CAS Registry Number.
