21995-45-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 21995-45-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,9,9 and 5 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 21995-45:
(7*2)+(6*1)+(5*9)+(4*9)+(3*5)+(2*4)+(1*5)=129
129 % 10 = 9
So 21995-45-9 is a valid CAS Registry Number.
