519183-15-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 519183-15-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,1,9,1,8 and 3 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 519183-15:
(8*5)+(7*1)+(6*9)+(5*1)+(4*8)+(3*3)+(2*1)+(1*5)=154
154 % 10 = 4
So 519183-15-4 is a valid CAS Registry Number.
