Check Digit Verification of cas no
The CAS Registry Mumber 6247-39-8 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, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 6247-39:
(6*6)+(5*2)+(4*4)+(3*7)+(2*3)+(1*9)=98
98 % 10 = 8
So 6247-39-8 is a valid CAS Registry Number.
