1098194-91-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1098194-91-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,9,8,1,9 and 4 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1098194-91:
(9*1)+(8*0)+(7*9)+(6*8)+(5*1)+(4*9)+(3*4)+(2*9)+(1*1)=192
192 % 10 = 2
So 1098194-91-2 is a valid CAS Registry Number.
