98123-01-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 98123-01-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,1,2 and 3 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 98123-01:
(7*9)+(6*8)+(5*1)+(4*2)+(3*3)+(2*0)+(1*1)=134
134 % 10 = 4
So 98123-01-4 is a valid CAS Registry Number.
