109948-69-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 109948-69-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,9,4 and 8 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 109948-69:
(8*1)+(7*0)+(6*9)+(5*9)+(4*4)+(3*8)+(2*6)+(1*9)=168
168 % 10 = 8
So 109948-69-8 is a valid CAS Registry Number.
