623907-82-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 623907-82-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,2,3,9,0 and 7 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 623907-82:
(8*6)+(7*2)+(6*3)+(5*9)+(4*0)+(3*7)+(2*8)+(1*2)=164
164 % 10 = 4
So 623907-82-4 is a valid CAS Registry Number.
