73194-01-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 73194-01-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,1,9 and 4 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 73194-01:
(7*7)+(6*3)+(5*1)+(4*9)+(3*4)+(2*0)+(1*1)=121
121 % 10 = 1
So 73194-01-1 is a valid CAS Registry Number.
