198541-40-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 198541-40-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,8,5,4 and 1 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 198541-40:
(8*1)+(7*9)+(6*8)+(5*5)+(4*4)+(3*1)+(2*4)+(1*0)=171
171 % 10 = 1
So 198541-40-1 is a valid CAS Registry Number.
