57648-76-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 57648-76-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,7,6,4 and 8 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 57648-76:
(7*5)+(6*7)+(5*6)+(4*4)+(3*8)+(2*7)+(1*6)=167
167 % 10 = 7
So 57648-76-7 is a valid CAS Registry Number.
