62676-20-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 62676-20-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,2,6,7 and 6 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 62676-20:
(7*6)+(6*2)+(5*6)+(4*7)+(3*6)+(2*2)+(1*0)=134
134 % 10 = 4
So 62676-20-4 is a valid CAS Registry Number.
