133981-05-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 133981-05-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,9,8 and 1 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 133981-05:
(8*1)+(7*3)+(6*3)+(5*9)+(4*8)+(3*1)+(2*0)+(1*5)=132
132 % 10 = 2
So 133981-05-2 is a valid CAS Registry Number.
