62930-18-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 62930-18-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,2,9,3 and 0 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 62930-18:
(7*6)+(6*2)+(5*9)+(4*3)+(3*0)+(2*1)+(1*8)=121
121 % 10 = 1
So 62930-18-1 is a valid CAS Registry Number.
