205191-78-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 205191-78-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,5,1,9 and 1 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 205191-78:
(8*2)+(7*0)+(6*5)+(5*1)+(4*9)+(3*1)+(2*7)+(1*8)=112
112 % 10 = 2
So 205191-78-2 is a valid CAS Registry Number.
