1027568-72-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1027568-72-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,7,5,6 and 8 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1027568-72:
(9*1)+(8*0)+(7*2)+(6*7)+(5*5)+(4*6)+(3*8)+(2*7)+(1*2)=154
154 % 10 = 4
So 1027568-72-4 is a valid CAS Registry Number.
