623158-28-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 623158-28-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,2,3,1,5 and 8 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 623158-28:
(8*6)+(7*2)+(6*3)+(5*1)+(4*5)+(3*8)+(2*2)+(1*8)=141
141 % 10 = 1
So 623158-28-1 is a valid CAS Registry Number.
