74199-20-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 74199-20-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,1,9 and 9 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 74199-20:
(7*7)+(6*4)+(5*1)+(4*9)+(3*9)+(2*2)+(1*0)=145
145 % 10 = 5
So 74199-20-5 is a valid CAS Registry Number.
