918329-99-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 918329-99-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,1,8,3,2 and 9 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 918329-99:
(8*9)+(7*1)+(6*8)+(5*3)+(4*2)+(3*9)+(2*9)+(1*9)=204
204 % 10 = 4
So 918329-99-4 is a valid CAS Registry Number.
