Check Digit Verification of cas no
The CAS Registry Mumber 6245-62-1 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, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 6245-62:
(6*6)+(5*2)+(4*4)+(3*5)+(2*6)+(1*2)=91
91 % 10 = 1
So 6245-62-1 is a valid CAS Registry Number.
