Check Digit Verification of cas no
The CAS Registry Mumber 497265-21-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,9,7,2,6 and 5 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 497265-21:
(8*4)+(7*9)+(6*7)+(5*2)+(4*6)+(3*5)+(2*2)+(1*1)=191
191 % 10 = 1
So 497265-21-1 is a valid CAS Registry Number.
