132817-45-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 132817-45-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,2,8,1 and 7 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 132817-45:
(8*1)+(7*3)+(6*2)+(5*8)+(4*1)+(3*7)+(2*4)+(1*5)=119
119 % 10 = 9
So 132817-45-9 is a valid CAS Registry Number.
