79877-49-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 79877-49-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,9,8,7 and 7 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 79877-49:
(7*7)+(6*9)+(5*8)+(4*7)+(3*7)+(2*4)+(1*9)=209
209 % 10 = 9
So 79877-49-9 is a valid CAS Registry Number.
