157001-56-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 157001-56-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,7,0,0 and 1 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 157001-56:
(8*1)+(7*5)+(6*7)+(5*0)+(4*0)+(3*1)+(2*5)+(1*6)=104
104 % 10 = 4
So 157001-56-4 is a valid CAS Registry Number.
