192505-98-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 192505-98-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,2,5,0 and 5 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 192505-98:
(8*1)+(7*9)+(6*2)+(5*5)+(4*0)+(3*5)+(2*9)+(1*8)=149
149 % 10 = 9
So 192505-98-9 is a valid CAS Registry Number.
