155928-47-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 155928-47-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,5,9,2 and 8 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 155928-47:
(8*1)+(7*5)+(6*5)+(5*9)+(4*2)+(3*8)+(2*4)+(1*7)=165
165 % 10 = 5
So 155928-47-5 is a valid CAS Registry Number.
