615580-26-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 615580-26-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,1,5,5,8 and 0 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 615580-26:
(8*6)+(7*1)+(6*5)+(5*5)+(4*8)+(3*0)+(2*2)+(1*6)=152
152 % 10 = 2
So 615580-26-2 is a valid CAS Registry Number.
