947539-59-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 947539-59-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,4,7,5,3 and 9 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 947539-59:
(8*9)+(7*4)+(6*7)+(5*5)+(4*3)+(3*9)+(2*5)+(1*9)=225
225 % 10 = 5
So 947539-59-5 is a valid CAS Registry Number.
