75949-33-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 75949-33-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,9,4 and 9 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 75949-33:
(7*7)+(6*5)+(5*9)+(4*4)+(3*9)+(2*3)+(1*3)=176
176 % 10 = 6
So 75949-33-6 is a valid CAS Registry Number.
