127766-74-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 127766-74-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,7,6 and 6 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 127766-74:
(8*1)+(7*2)+(6*7)+(5*7)+(4*6)+(3*6)+(2*7)+(1*4)=159
159 % 10 = 9
So 127766-74-9 is a valid CAS Registry Number.
