73891-13-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 73891-13-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,8,9 and 1 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 73891-13:
(7*7)+(6*3)+(5*8)+(4*9)+(3*1)+(2*1)+(1*3)=151
151 % 10 = 1
So 73891-13-1 is a valid CAS Registry Number.
