623574-30-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 623574-30-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,2,3,5,7 and 4 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 623574-30:
(8*6)+(7*2)+(6*3)+(5*5)+(4*7)+(3*4)+(2*3)+(1*0)=151
151 % 10 = 1
So 623574-30-1 is a valid CAS Registry Number.
