Check Digit Verification of cas no
The CAS Registry Mumber 15578-26-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,5,5,7 and 8 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 15578-26:
(7*1)+(6*5)+(5*5)+(4*7)+(3*8)+(2*2)+(1*6)=124
124 % 10 = 4
So 15578-26-4 is a valid CAS Registry Number.
