Check Digit Verification of cas no
The CAS Registry Mumber 6249-25-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,2,4 and 9 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 6249-25:
(6*6)+(5*2)+(4*4)+(3*9)+(2*2)+(1*5)=98
98 % 10 = 8
So 6249-25-8 is a valid CAS Registry Number.
