948552-60-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 948552-60-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,4,8,5,5 and 2 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 948552-60:
(8*9)+(7*4)+(6*8)+(5*5)+(4*5)+(3*2)+(2*6)+(1*0)=211
211 % 10 = 1
So 948552-60-1 is a valid CAS Registry Number.
