2261-94-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 2261-94-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,2,6 and 1 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 2261-94:
(6*2)+(5*2)+(4*6)+(3*1)+(2*9)+(1*4)=71
71 % 10 = 1
So 2261-94-1 is a valid CAS Registry Number.
