Check Digit Verification of cas no
The CAS Registry Mumber 6359-85-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,3,5 and 9 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 6359-85:
(6*6)+(5*3)+(4*5)+(3*9)+(2*8)+(1*5)=119
119 % 10 = 9
So 6359-85-9 is a valid CAS Registry Number.
