52187-19-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 52187-19-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,2,1,8 and 7 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 52187-19:
(7*5)+(6*2)+(5*1)+(4*8)+(3*7)+(2*1)+(1*9)=116
116 % 10 = 6
So 52187-19-6 is a valid CAS Registry Number.
