123958-50-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 123958-50-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,3,9,5 and 8 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 123958-50:
(8*1)+(7*2)+(6*3)+(5*9)+(4*5)+(3*8)+(2*5)+(1*0)=139
139 % 10 = 9
So 123958-50-9 is a valid CAS Registry Number.
