79981-90-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 79981-90-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,9,9,8 and 1 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 79981-90:
(7*7)+(6*9)+(5*9)+(4*8)+(3*1)+(2*9)+(1*0)=201
201 % 10 = 1
So 79981-90-1 is a valid CAS Registry Number.
