Check Digit Verification of cas no
The CAS Registry Mumber 57129-07-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,7,1,2 and 9 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 57129-07:
(7*5)+(6*7)+(5*1)+(4*2)+(3*9)+(2*0)+(1*7)=124
124 % 10 = 4
So 57129-07-4 is a valid CAS Registry Number.
