Check Digit Verification of cas no
The CAS Registry Mumber 6247-46-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,2,4 and 7 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 6247-46:
(6*6)+(5*2)+(4*4)+(3*7)+(2*4)+(1*6)=97
97 % 10 = 7
So 6247-46-7 is a valid CAS Registry Number.
