Check Digit Verification of cas no
The CAS Registry Mumber 15959-26-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,5,9,5 and 9 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 15959-26:
(7*1)+(6*5)+(5*9)+(4*5)+(3*9)+(2*2)+(1*6)=139
139 % 10 = 9
So 15959-26-9 is a valid CAS Registry Number.
