56933-74-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 56933-74-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,6,9,3 and 3 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 56933-74:
(7*5)+(6*6)+(5*9)+(4*3)+(3*3)+(2*7)+(1*4)=155
155 % 10 = 5
So 56933-74-5 is a valid CAS Registry Number.
