Check Digit Verification of cas no
The CAS Registry Mumber 124372-17-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,4,3,7 and 2 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 124372-17:
(8*1)+(7*2)+(6*4)+(5*3)+(4*7)+(3*2)+(2*1)+(1*7)=104
104 % 10 = 4
So 124372-17-4 is a valid CAS Registry Number.
