127628-15-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 127628-15-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,6,2 and 8 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 127628-15:
(8*1)+(7*2)+(6*7)+(5*6)+(4*2)+(3*8)+(2*1)+(1*5)=133
133 % 10 = 3
So 127628-15-3 is a valid CAS Registry Number.
