180633-91-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 180633-91-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,0,6,3 and 3 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 180633-91:
(8*1)+(7*8)+(6*0)+(5*6)+(4*3)+(3*3)+(2*9)+(1*1)=134
134 % 10 = 4
So 180633-91-4 is a valid CAS Registry Number.
