180137-35-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 180137-35-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,0,1,3 and 7 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 180137-35:
(8*1)+(7*8)+(6*0)+(5*1)+(4*3)+(3*7)+(2*3)+(1*5)=113
113 % 10 = 3
So 180137-35-3 is a valid CAS Registry Number.
