Check Digit Verification of cas no
The CAS Registry Mumber 6245-59-6 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 5 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 6245-59:
(6*6)+(5*2)+(4*4)+(3*5)+(2*5)+(1*9)=96
96 % 10 = 6
So 6245-59-6 is a valid CAS Registry Number.
