183439-49-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 183439-49-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,3,4,3 and 9 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 183439-49:
(8*1)+(7*8)+(6*3)+(5*4)+(4*3)+(3*9)+(2*4)+(1*9)=158
158 % 10 = 8
So 183439-49-8 is a valid CAS Registry Number.
