1027557-52-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1027557-52-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,7,5,5 and 7 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1027557-52:
(9*1)+(8*0)+(7*2)+(6*7)+(5*5)+(4*5)+(3*7)+(2*5)+(1*2)=143
143 % 10 = 3
So 1027557-52-3 is a valid CAS Registry Number.
