1384433-57-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1384433-57-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,8,4,4,3 and 3 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1384433-57:
(9*1)+(8*3)+(7*8)+(6*4)+(5*4)+(4*3)+(3*3)+(2*5)+(1*7)=171
171 % 10 = 1
So 1384433-57-1 is a valid CAS Registry Number.
