Check Digit Verification of cas no
The CAS Registry Mumber 10290-03-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,0,2,9 and 0 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 10290-03:
(7*1)+(6*0)+(5*2)+(4*9)+(3*0)+(2*0)+(1*3)=56
56 % 10 = 6
So 10290-03-6 is a valid CAS Registry Number.
