127657-49-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 127657-49-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,6,5 and 7 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 127657-49:
(8*1)+(7*2)+(6*7)+(5*6)+(4*5)+(3*7)+(2*4)+(1*9)=152
152 % 10 = 2
So 127657-49-2 is a valid CAS Registry Number.
