Check Digit Verification of cas no
The CAS Registry Mumber 121303-75-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,3,0 and 3 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 121303-75:
(8*1)+(7*2)+(6*1)+(5*3)+(4*0)+(3*3)+(2*7)+(1*5)=71
71 % 10 = 1
So 121303-75-1 is a valid CAS Registry Number.
