217460-47-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 217460-47-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,7,4,6 and 0 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 217460-47:
(8*2)+(7*1)+(6*7)+(5*4)+(4*6)+(3*0)+(2*4)+(1*7)=124
124 % 10 = 4
So 217460-47-4 is a valid CAS Registry Number.
