109756-12-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 109756-12-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,7,5 and 6 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 109756-12:
(8*1)+(7*0)+(6*9)+(5*7)+(4*5)+(3*6)+(2*1)+(1*2)=139
139 % 10 = 9
So 109756-12-9 is a valid CAS Registry Number.
