73844-64-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 73844-64-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,8,4 and 4 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 73844-64:
(7*7)+(6*3)+(5*8)+(4*4)+(3*4)+(2*6)+(1*4)=151
151 % 10 = 1
So 73844-64-1 is a valid CAS Registry Number.
