73121-12-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 73121-12-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,1,2 and 1 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 73121-12:
(7*7)+(6*3)+(5*1)+(4*2)+(3*1)+(2*1)+(1*2)=87
87 % 10 = 7
So 73121-12-7 is a valid CAS Registry Number.
