198475-85-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 198475-85-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,8,4,7 and 5 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 198475-85:
(8*1)+(7*9)+(6*8)+(5*4)+(4*7)+(3*5)+(2*8)+(1*5)=203
203 % 10 = 3
So 198475-85-3 is a valid CAS Registry Number.
