Check Digit Verification of cas no
The CAS Registry Mumber 6359-90-6 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, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 6359-90:
(6*6)+(5*3)+(4*5)+(3*9)+(2*9)+(1*0)=116
116 % 10 = 6
So 6359-90-6 is a valid CAS Registry Number.
