Check Digit Verification of cas no
The CAS Registry Mumber 125973-97-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,5,9,7 and 3 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 125973-97:
(8*1)+(7*2)+(6*5)+(5*9)+(4*7)+(3*3)+(2*9)+(1*7)=159
159 % 10 = 9
So 125973-97-9 is a valid CAS Registry Number.
