Check Digit Verification of cas no
The CAS Registry Mumber 3354-97-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,3,5 and 4 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 3354-97:
(6*3)+(5*3)+(4*5)+(3*4)+(2*9)+(1*7)=90
90 % 10 = 0
So 3354-97-0 is a valid CAS Registry Number.
