121406-77-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 121406-77-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,4,0 and 6 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 121406-77:
(8*1)+(7*2)+(6*1)+(5*4)+(4*0)+(3*6)+(2*7)+(1*7)=87
87 % 10 = 7
So 121406-77-7 is a valid CAS Registry Number.
