271601-04-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 271601-04-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,7,1,6,0 and 1 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 271601-04:
(8*2)+(7*7)+(6*1)+(5*6)+(4*0)+(3*1)+(2*0)+(1*4)=108
108 % 10 = 8
So 271601-04-8 is a valid CAS Registry Number.
