65679-20-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 65679-20-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,5,6,7 and 9 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 65679-20:
(7*6)+(6*5)+(5*6)+(4*7)+(3*9)+(2*2)+(1*0)=161
161 % 10 = 1
So 65679-20-1 is a valid CAS Registry Number.
