314270-77-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 314270-77-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,1,4,2,7 and 0 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 314270-77:
(8*3)+(7*1)+(6*4)+(5*2)+(4*7)+(3*0)+(2*7)+(1*7)=114
114 % 10 = 4
So 314270-77-4 is a valid CAS Registry Number.
