334977-46-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 334977-46-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,3,4,9,7 and 7 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 334977-46:
(8*3)+(7*3)+(6*4)+(5*9)+(4*7)+(3*7)+(2*4)+(1*6)=177
177 % 10 = 7
So 334977-46-7 is a valid CAS Registry Number.
