Check Digit Verification of cas no
The CAS Registry Mumber 1257-25-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,2,5 and 7 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1257-25:
(6*1)+(5*2)+(4*5)+(3*7)+(2*2)+(1*5)=66
66 % 10 = 6
So 1257-25-6 is a valid CAS Registry Number.
