Check Digit Verification of cas no
The CAS Registry Mumber 25779-05-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,7,7 and 9 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 25779-05:
(7*2)+(6*5)+(5*7)+(4*7)+(3*9)+(2*0)+(1*5)=139
139 % 10 = 9
So 25779-05-9 is a valid CAS Registry Number.
