192988-50-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 192988-50-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,2,9,8 and 8 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 192988-50:
(8*1)+(7*9)+(6*2)+(5*9)+(4*8)+(3*8)+(2*5)+(1*0)=194
194 % 10 = 4
So 192988-50-4 is a valid CAS Registry Number.
