150256-26-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 150256-26-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,0,2,5 and 6 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 150256-26:
(8*1)+(7*5)+(6*0)+(5*2)+(4*5)+(3*6)+(2*2)+(1*6)=101
101 % 10 = 1
So 150256-26-1 is a valid CAS Registry Number.
