127780-58-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 127780-58-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,7,8 and 0 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 127780-58:
(8*1)+(7*2)+(6*7)+(5*7)+(4*8)+(3*0)+(2*5)+(1*8)=149
149 % 10 = 9
So 127780-58-9 is a valid CAS Registry Number.
