133885-05-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 133885-05-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,8,8 and 5 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 133885-05:
(8*1)+(7*3)+(6*3)+(5*8)+(4*8)+(3*5)+(2*0)+(1*5)=139
139 % 10 = 9
So 133885-05-9 is a valid CAS Registry Number.
