186413-98-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 186413-98-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,6,4,1 and 3 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 186413-98:
(8*1)+(7*8)+(6*6)+(5*4)+(4*1)+(3*3)+(2*9)+(1*8)=159
159 % 10 = 9
So 186413-98-9 is a valid CAS Registry Number.
