Check Digit Verification of cas no
The CAS Registry Mumber 1807539-01-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,8,0,7,5,3 and 9 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1807539-01:
(9*1)+(8*8)+(7*0)+(6*7)+(5*5)+(4*3)+(3*9)+(2*0)+(1*1)=180
180 % 10 = 0
So 1807539-01-0 is a valid CAS Registry Number.
