85541-31-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 85541-31-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,5,5,4 and 1 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 85541-31:
(7*8)+(6*5)+(5*5)+(4*4)+(3*1)+(2*3)+(1*1)=137
137 % 10 = 7
So 85541-31-7 is a valid CAS Registry Number.
