Check Digit Verification of cas no
The CAS Registry Mumber 133318-40-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,3,1 and 8 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 133318-40:
(8*1)+(7*3)+(6*3)+(5*3)+(4*1)+(3*8)+(2*4)+(1*0)=98
98 % 10 = 8
So 133318-40-8 is a valid CAS Registry Number.
