109021-91-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 109021-91-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,0,2 and 1 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 109021-91:
(8*1)+(7*0)+(6*9)+(5*0)+(4*2)+(3*1)+(2*9)+(1*1)=92
92 % 10 = 2
So 109021-91-2 is a valid CAS Registry Number.
