251470-36-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 251470-36-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,1,4,7 and 0 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 251470-36:
(8*2)+(7*5)+(6*1)+(5*4)+(4*7)+(3*0)+(2*3)+(1*6)=117
117 % 10 = 7
So 251470-36-7 is a valid CAS Registry Number.
