92531-85-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 92531-85-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,2,5,3 and 1 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 92531-85:
(7*9)+(6*2)+(5*5)+(4*3)+(3*1)+(2*8)+(1*5)=136
136 % 10 = 6
So 92531-85-6 is a valid CAS Registry Number.
