1027388-95-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1027388-95-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,7,3,8 and 8 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1027388-95:
(9*1)+(8*0)+(7*2)+(6*7)+(5*3)+(4*8)+(3*8)+(2*9)+(1*5)=159
159 % 10 = 9
So 1027388-95-9 is a valid CAS Registry Number.
