1027586-28-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1027586-28-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,7,5,8 and 6 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1027586-28:
(9*1)+(8*0)+(7*2)+(6*7)+(5*5)+(4*8)+(3*6)+(2*2)+(1*8)=152
152 % 10 = 2
So 1027586-28-2 is a valid CAS Registry Number.
