75620-57-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 75620-57-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,6,2 and 0 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 75620-57:
(7*7)+(6*5)+(5*6)+(4*2)+(3*0)+(2*5)+(1*7)=134
134 % 10 = 4
So 75620-57-4 is a valid CAS Registry Number.
