Check Digit Verification of cas no
The CAS Registry Mumber 1421227-97-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,1,2,2 and 7 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1421227-97:
(9*1)+(8*4)+(7*2)+(6*1)+(5*2)+(4*2)+(3*7)+(2*9)+(1*7)=125
125 % 10 = 5
So 1421227-97-5 is a valid CAS Registry Number.
