2639-26-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 2639-26-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,6,3 and 9 respectively; the second part has 2 digits, 2 and 6 respectively.Calculate Digit Verification of CAS Registry Number 2639-26:
(6*2)+(5*6)+(4*3)+(3*9)+(2*2)+(1*6)=91
91 % 10 = 1
So 2639-26-1 is a valid CAS Registry Number.
