Check Digit Verification of cas no
The CAS Registry Mumber 1242-25-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,2,4 and 2 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1242-25:
(6*1)+(5*2)+(4*4)+(3*2)+(2*2)+(1*5)=47
47 % 10 = 7
So 1242-25-7 is a valid CAS Registry Number.
