109668-81-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 109668-81-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,6,6 and 8 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 109668-81:
(8*1)+(7*0)+(6*9)+(5*6)+(4*6)+(3*8)+(2*8)+(1*1)=157
157 % 10 = 7
So 109668-81-7 is a valid CAS Registry Number.
