26939-21-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 26939-21-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,6,9,3 and 9 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 26939-21:
(7*2)+(6*6)+(5*9)+(4*3)+(3*9)+(2*2)+(1*1)=139
139 % 10 = 9
So 26939-21-9 is a valid CAS Registry Number.
