Check Digit Verification of cas no
The CAS Registry Mumber 133380-70-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,3,8 and 0 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 133380-70:
(8*1)+(7*3)+(6*3)+(5*3)+(4*8)+(3*0)+(2*7)+(1*0)=108
108 % 10 = 8
So 133380-70-8 is a valid CAS Registry Number.
