Check Digit Verification of cas no
The CAS Registry Mumber 26298-81-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,6,2,9 and 8 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 26298-81:
(7*2)+(6*6)+(5*2)+(4*9)+(3*8)+(2*8)+(1*1)=137
137 % 10 = 7
So 26298-81-7 is a valid CAS Registry Number.
