Check Digit Verification of cas no
The CAS Registry Mumber 497870-31-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,9,7,8,7 and 0 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 497870-31:
(8*4)+(7*9)+(6*7)+(5*8)+(4*7)+(3*0)+(2*3)+(1*1)=212
212 % 10 = 2
So 497870-31-2 is a valid CAS Registry Number.
