Check Digit Verification of cas no
The CAS Registry Mumber 104953-97-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,4,9,5 and 3 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 104953-97:
(8*1)+(7*0)+(6*4)+(5*9)+(4*5)+(3*3)+(2*9)+(1*7)=131
131 % 10 = 1
So 104953-97-1 is a valid CAS Registry Number.
