109929-65-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 109929-65-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,9,2 and 9 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 109929-65:
(8*1)+(7*0)+(6*9)+(5*9)+(4*2)+(3*9)+(2*6)+(1*5)=159
159 % 10 = 9
So 109929-65-9 is a valid CAS Registry Number.
