721959-69-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 721959-69-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,2,1,9,5 and 9 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 721959-69:
(8*7)+(7*2)+(6*1)+(5*9)+(4*5)+(3*9)+(2*6)+(1*9)=189
189 % 10 = 9
So 721959-69-9 is a valid CAS Registry Number.
