479634-18-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 479634-18-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,7,9,6,3 and 4 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 479634-18:
(8*4)+(7*7)+(6*9)+(5*6)+(4*3)+(3*4)+(2*1)+(1*8)=199
199 % 10 = 9
So 479634-18-9 is a valid CAS Registry Number.
