474543-10-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 474543-10-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,7,4,5,4 and 3 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 474543-10:
(8*4)+(7*7)+(6*4)+(5*5)+(4*4)+(3*3)+(2*1)+(1*0)=157
157 % 10 = 7
So 474543-10-7 is a valid CAS Registry Number.
