77548-33-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 77548-33-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,5,4 and 8 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 77548-33:
(7*7)+(6*7)+(5*5)+(4*4)+(3*8)+(2*3)+(1*3)=165
165 % 10 = 5
So 77548-33-5 is a valid CAS Registry Number.
