109773-89-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 109773-89-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,7,7 and 3 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 109773-89:
(8*1)+(7*0)+(6*9)+(5*7)+(4*7)+(3*3)+(2*8)+(1*9)=159
159 % 10 = 9
So 109773-89-9 is a valid CAS Registry Number.
