77979-03-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 77979-03-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,9,7 and 9 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 77979-03:
(7*7)+(6*7)+(5*9)+(4*7)+(3*9)+(2*0)+(1*3)=194
194 % 10 = 4
So 77979-03-4 is a valid CAS Registry Number.
