753412-21-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 753412-21-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,5,3,4,1 and 2 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 753412-21:
(8*7)+(7*5)+(6*3)+(5*4)+(4*1)+(3*2)+(2*2)+(1*1)=144
144 % 10 = 4
So 753412-21-4 is a valid CAS Registry Number.
