77020-17-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 77020-17-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,0,2 and 0 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 77020-17:
(7*7)+(6*7)+(5*0)+(4*2)+(3*0)+(2*1)+(1*7)=108
108 % 10 = 8
So 77020-17-8 is a valid CAS Registry Number.
