Check Digit Verification of cas no
The CAS Registry Mumber 126513-98-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,6,5,1 and 3 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 126513-98:
(8*1)+(7*2)+(6*6)+(5*5)+(4*1)+(3*3)+(2*9)+(1*8)=122
122 % 10 = 2
So 126513-98-2 is a valid CAS Registry Number.
