905451-15-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 905451-15-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,0,5,4,5 and 1 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 905451-15:
(8*9)+(7*0)+(6*5)+(5*4)+(4*5)+(3*1)+(2*1)+(1*5)=152
152 % 10 = 2
So 905451-15-2 is a valid CAS Registry Number.
