Check Digit Verification of cas no
The CAS Registry Mumber 62679-61-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,2,6,7 and 9 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 62679-61:
(7*6)+(6*2)+(5*6)+(4*7)+(3*9)+(2*6)+(1*1)=152
152 % 10 = 2
So 62679-61-2 is a valid CAS Registry Number.
