477217-36-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 477217-36-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,7,7,2,1 and 7 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 477217-36:
(8*4)+(7*7)+(6*7)+(5*2)+(4*1)+(3*7)+(2*3)+(1*6)=170
170 % 10 = 0
So 477217-36-0 is a valid CAS Registry Number.
