1186094-55-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1186094-55-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,8,6,0,9 and 4 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1186094-55:
(9*1)+(8*1)+(7*8)+(6*6)+(5*0)+(4*9)+(3*4)+(2*5)+(1*5)=172
172 % 10 = 2
So 1186094-55-2 is a valid CAS Registry Number.
