154356-85-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 154356-85-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,4,3,5 and 6 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 154356-85:
(8*1)+(7*5)+(6*4)+(5*3)+(4*5)+(3*6)+(2*8)+(1*5)=141
141 % 10 = 1
So 154356-85-1 is a valid CAS Registry Number.
