Check Digit Verification of cas no
The CAS Registry Mumber 6441-94-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,4,4 and 1 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 6441-94:
(6*6)+(5*4)+(4*4)+(3*1)+(2*9)+(1*4)=97
97 % 10 = 7
So 6441-94-7 is a valid CAS Registry Number.
