109977-95-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 109977-95-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,9,7 and 7 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 109977-95:
(8*1)+(7*0)+(6*9)+(5*9)+(4*7)+(3*7)+(2*9)+(1*5)=179
179 % 10 = 9
So 109977-95-9 is a valid CAS Registry Number.
