180137-75-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 180137-75-1 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, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 180137-75:
(8*1)+(7*8)+(6*0)+(5*1)+(4*3)+(3*7)+(2*7)+(1*5)=121
121 % 10 = 1
So 180137-75-1 is a valid CAS Registry Number.
