127702-99-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 127702-99-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,7,0 and 2 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 127702-99:
(8*1)+(7*2)+(6*7)+(5*7)+(4*0)+(3*2)+(2*9)+(1*9)=132
132 % 10 = 2
So 127702-99-2 is a valid CAS Registry Number.
