Check Digit Verification of cas no
The CAS Registry Mumber 124643-73-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,4,6,4 and 3 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 124643-73:
(8*1)+(7*2)+(6*4)+(5*6)+(4*4)+(3*3)+(2*7)+(1*3)=118
118 % 10 = 8
So 124643-73-8 is a valid CAS Registry Number.
