149976-77-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 149976-77-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,9,9,7 and 6 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 149976-77:
(8*1)+(7*4)+(6*9)+(5*9)+(4*7)+(3*6)+(2*7)+(1*7)=202
202 % 10 = 2
So 149976-77-2 is a valid CAS Registry Number.
