6271-94-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 6271-94-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,2,7 and 1 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 6271-94:
(6*6)+(5*2)+(4*7)+(3*1)+(2*9)+(1*4)=99
99 % 10 = 9
So 6271-94-9 is a valid CAS Registry Number.
