1027381-57-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1027381-57-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,7,3,8 and 1 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1027381-57:
(9*1)+(8*0)+(7*2)+(6*7)+(5*3)+(4*8)+(3*1)+(2*5)+(1*7)=132
132 % 10 = 2
So 1027381-57-2 is a valid CAS Registry Number.
