Check Digit Verification of cas no
The CAS Registry Mumber 1807530-07-9 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 0 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1807530-07:
(9*1)+(8*8)+(7*0)+(6*7)+(5*5)+(4*3)+(3*0)+(2*0)+(1*7)=159
159 % 10 = 9
So 1807530-07-9 is a valid CAS Registry Number.
