1167976-63-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1167976-63-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,6,7,9,7 and 6 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1167976-63:
(9*1)+(8*1)+(7*6)+(6*7)+(5*9)+(4*7)+(3*6)+(2*6)+(1*3)=207
207 % 10 = 7
So 1167976-63-7 is a valid CAS Registry Number.
