84433-74-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 84433-74-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,4,4,3 and 3 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 84433-74:
(7*8)+(6*4)+(5*4)+(4*3)+(3*3)+(2*7)+(1*4)=139
139 % 10 = 9
So 84433-74-9 is a valid CAS Registry Number.
