209968-54-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 209968-54-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,9,9,6 and 8 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 209968-54:
(8*2)+(7*0)+(6*9)+(5*9)+(4*6)+(3*8)+(2*5)+(1*4)=177
177 % 10 = 7
So 209968-54-7 is a valid CAS Registry Number.
