106696-53-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 106696-53-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,6,6,9 and 6 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 106696-53:
(8*1)+(7*0)+(6*6)+(5*6)+(4*9)+(3*6)+(2*5)+(1*3)=141
141 % 10 = 1
So 106696-53-1 is a valid CAS Registry Number.
