145161-98-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 145161-98-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,5,1,6 and 1 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 145161-98:
(8*1)+(7*4)+(6*5)+(5*1)+(4*6)+(3*1)+(2*9)+(1*8)=124
124 % 10 = 4
So 145161-98-4 is a valid CAS Registry Number.
