75277-13-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 75277-13-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,2,7 and 7 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 75277-13:
(7*7)+(6*5)+(5*2)+(4*7)+(3*7)+(2*1)+(1*3)=143
143 % 10 = 3
So 75277-13-3 is a valid CAS Registry Number.
