109200-91-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 109200-91-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,2,0 and 0 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 109200-91:
(8*1)+(7*0)+(6*9)+(5*2)+(4*0)+(3*0)+(2*9)+(1*1)=91
91 % 10 = 1
So 109200-91-1 is a valid CAS Registry Number.
