76638-19-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 76638-19-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,6,6,3 and 8 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 76638-19:
(7*7)+(6*6)+(5*6)+(4*3)+(3*8)+(2*1)+(1*9)=162
162 % 10 = 2
So 76638-19-2 is a valid CAS Registry Number.
