1027270-77-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1027270-77-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,7,2,7 and 0 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1027270-77:
(9*1)+(8*0)+(7*2)+(6*7)+(5*2)+(4*7)+(3*0)+(2*7)+(1*7)=124
124 % 10 = 4
So 1027270-77-4 is a valid CAS Registry Number.
